Answer:
B) -1/2
Step-by-step explanation:
(2, 3) and (4, 2)
Slope:
m=(y2-y1)/(x2-x1)
m=(2-3)/(4-2)
m= (-1)/2
m= -1/2
The Slope of the given line is -1/2.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
We take two points from the graph as (2, 3) and (4, 2).
Now, the slope of line is
= (3-2)/ (4-2)
= -1 / 2
= -0.5
Using Slope intercept form
y= mx+ b
y= -0.5x+ b
and, b = 4
so, the Equation of line is y= -0.5x+ 4.

Answer:
x=-40,0
y=0,15
Step-by-step explanation:
intercepts are points where the graph cuts the axes
Answer:
(- 40, 0 ) and (0, 15 )
Step-by-step explanation:
The x- intercept is the point on the x- axis where the line crosses, then
x- intercept = (- 40, 0 )
The y- intercept is the pont on the y- axis where the line crosses, then
y- intercept = (0, 15 )

Length of rectangle parking lot = 94 m
Width of rectangle pool = 85 m
Step-by-step explanation:
Given:
Perimeter of rectangle = 300 m
Width of rectangle parking lot = 56 m
Find:
Length of rectangle parking lot
Area of rectangle pool = 8,245 m²
Length of rectangle pool = 97 m
Find:
Width of rectangle pool.
Computation:
1. Perimeter of rectangle = 2[l+b]
2[56 + l] = 300
56 + l = 150
Length of rectangle parking lot = 94 m
2. Area of rectangle = L x B
97 x Width of rectangle pool = 8,245
Width of rectangle pool = 85 m
Answer:
The length of the rectangle parking lot is 94 meters.
Rectangle pool width = 85 m

write a quadratic function in the given form whose graph satisfies the given condition.
has a vertex of (5, -2) & passes through the point (3, 6) in vertex form
pls help...important...dont steal
Answer:
f(x) = 2(x-5)²-2
Step-by-step explanation:
The equation of a parabola in vertex form is y=a(x-h)²+k where (h,k) is the vertex and "a" represents how stretched or compressed the parabola is and what direction it travels.
Given a vertex of (5,-2) the equation so far is y=a(x-5)²-2
Since we want the parabola to pass through the point (3,6) we must find a value of "a" that satisfies this:
y=a(x-5)²-2
6=a(3-5)²-2
6=a(-2)²-2
6=4a-2
8=4a
2=a
This means that the quadratic function is f(x) = 2(x-5)²-2
