Please solve the question in the picture below.
Answer:
a
Step-by-step explanation:
because y=mx+b m =slope and b is the y intercept
Answer:
A. is the right answer
slope is 1.5 and y intercept is -2
Draw a line through the point (2, 2) with a slope of 1. Draw a line through the point (1,−1) with a slope of 1.
Answer:
should look like this
Step-by-step explanation:
equations are y=x and y = -x if needed
The equation of the lines are y = x and y = x - 2
A linear equation is given by:
y = mx + b;
where y, x are variables, m is the slope of the line and b is the y intercept
The equation of a line passing through the point (2, 2) with a slope of 1 is:
[tex]y-y_1=m(x-x_1)\\\\y-2=1(x-2)\\\\y = x[/tex]
The equation of a line passing through the point (1, -1) with a slope of 1 is:
[tex]y-y_1=m(x-x_1)\\\\y-(-1)=1(x-1)\\\\y = x-2[/tex]
Therefore both lines have equation of y = x and y = x - 2. The graphs of the lines are attached.

How does the graph of f(x)=|x| compare with the graph of g(x) = 1/2|x| select all that apply
Answer:
I don't see the choices but both graphs are absolute value graphs. I think g(x) = 1/2|x| is the shrink of f(x)=|x|
How to solve systems of inequalities
Answer:
Determine whether an ordered pair is a solution of a system of linear inequalities.
Solve a system of linear inequalities by graphing
Solve applications of systems of inequalities
You can use desmos
Step-by-step explanation:
Graph x>2 on a number line.
Solve the inequality 2a<5a+12.
Determine whether the ordered pair \left(3,\frac{1}{2}\right) is a solution to the system \left\{\begin{array}{c}x+2y=4\hfill \\ y=6x\hfill \end{array}.
Determine Whether an Ordered Pair is a Solution of a System of Linear Inequalities
The definition of a system of linear inequalities is very similar to the definition of a system of linear equations.
System of Linear Inequalities
Two or more linear inequalities grouped together form a system of linear inequalities.
A system of linear inequalities looks like a system of linear equations, but it has inequalities instead of equations. A system of two linear inequalities is shown below.
\left\{\begin{array}{c}x+4y\ge 10\hfill \\ 3x-2y<12\hfill \end{array}
To solve a system of linear inequalities, we will find values of the variables that are solutions to both inequalities. We solve the system by using the graphs of each inequality and show the solution as a graph. We will find the region on the plane that contains all ordered pairs \left(x,y\right) that make both inequalities true.
Solutions of a System of Linear Inequalities
Solutions of a system of linear inequalities are the values of the variables that make all the inequalities true.
The solution of a system of linear inequalities is shown as a shaded region in the x-y coordinate system that includes all the points whose ordered pairs make the inequalities true.
To determine if an ordered pair is a solution to a system of two inequalities, we substitute the values of the variables into each inequality. If the ordered pair makes both inequalities true, it is a solution to the system. s

The temperature of a hot steak starts at 140f and decreases at 5f per minute what will the temperature of this steak after a certain number of minutes
Answer:
T(m) = (140 - 5m)
Step-by-step explanation:
Given that :
Initial temperature, a = 140 F
Rate of decrease = 5 F per minute
Given a certain Number of minutes, m
Temperature, T after m minutes ;
Using the formula :
Final temperature = Initial temperature - 5*number of minutes)
T(m) = (140 - 5m)
Given that ; m = 10
T(10) = 140 - 5(10)
T(10) = 140 - 50
T(10) = 90 F

If a scattergraph contains points that do not fall in a perfect line: Multiple Choice a straight line can still be used to approximate the relationship if a general linear trend can be discerned. the relationship between the variables is not good enough to warrant fitting a line to the data. this is an indication that there is no relationship whatsoever between the variables. the visual fit method and high-low methods should not be used, but least-squares regression can be used.
Answer:
a straight line can still be used to approximate the relationship if a general linear trend can be discerned.
Step-by-step explanation:
The correct option is - A straight line can still be used to approximate the relationship if a general linear trend can be discerned.
Reason -
If a scatter graph contains points that do not fall in a perfect line, then a straight line can still be used to approximate the relationship if a general linear trend can be discerned.
