Slope intercept form is y=mx+b
‘m’ is your slope and ‘b’ is your y-intercept !
Answer:
y = -0.5x - 7 or y = -1/2x - 7 (both are same)
Step-by-step explanation:
m = slope
slope = y2 - y1 / x2 - x1
-9 - (-8) / 4 - 2 = -1/2 = -0.5
m = -0.5
b = y-intercept
b = -7
y = mx + b
y = -0.5x + (-7)
y = -0.5x - 7
(negative slope)

The probability that a student chosen randomly from the class does not play an instrument is, 6/22.
What are sets and subsets?A set is a collection of well-defined objects.
A subset contains all the elements or a few elements of the given set.
The improper subset is when it contains all the elements of the given set and the proper subset is when it doesn't contain all the elements of the given set.
Given, n(U) = 22, n(I) = 15, n(S) = 11 and n(I∩S) = 9.
We know, n(IUS) = n(I) + n(S) - n(I∩S).
n(IUS) = 15 + 11 - 9.
n(IUS) = 17.
So, The number of people does not play an instrument is
n(S - I) = n(S) - n(S∩I) = 15 - 9 = 6.
Therefore, The probability that a student is chosen randomly from the class does not play an instrument is,
= 6/22.

Answers
Answer:
x = - 2 2/3
y = - 4 1/3
Step-by-step explanation:
-4x -2y = - 2
4x +8y = -24
Now if you just add those 2 equations, what will happen is that the xs will cancel. They are equal but opposite in sign
6y = - 26 Now divide by 6
6y/6 = -26/6 Combine
y = - 4 2/6 = - 4 2/6
y = - 4 1/3
Now use the top equation to find x
-4x - 2(-4 1/3) = - 2
-4x + 8 2/3 = - 2 Subtract 8 2/3 from both sides
- 4x = - 2 - 8 2/3 Combine
- 4x = - 10 2/3 Divide by - 4
x = - 10 2/3 / - 4
x = - 2 2/3

Answer:
(x, y) = (8/3, -13/3)
Step-by-step explanation:
The x-coefficients are opposites, so the x-terms can be eliminated simply by adding the equations.
(-4x -2y) +(4x +8y) = (-2) +(-24)
6y = -26
y = -26/6 = -13/3
Substituting into the first equation gives ...
-4x -2(-13/3) = -2
2x -13/3 = 1 . . . . . . . . divide by -2
2x = 16/3 . . . . . . . . . add 13/3
x = 8/3
The solution is (x, y) = (8/3, -13/3).

Step-by-step explanation:

Hello there!
cd=-56.
We are given that
c=4
We can plug it into the equation instead of c:
4d=-56
Now we must divide both sides by 4 in order to isolate d:
d=-14
Remember that whatever we do to one side, we do to the other.
