Answer:
-23
Step-by-step explanation:
We note that as x increases by 36 from -72 to 36, y decreases by 24 from 25 to 1.
Increasing x from -36 by another 36 to zero will correspond to a decrease in y by another 24 from 1 to -23.
The y-intercept is -23.
_____
You could go to the trouble to use these observations to compute the slope as -24/36 = -2/3. Then you could pick one of the points and write the equation in point-slope form as ...
y = -2/3(x +36) +1 . . . point-slope form with m=-2/3, (h, k) = (-36, 1)
y = -2/3x -24 +1 . . . . . eliminate parentheses
y = -2/3x -23 . . . . . . . y-intercept is -23
Answer:
<em>m</em> = 3/5

Answer: B
Step-by-step explanation: it is the 5 that is being multiplied so the 5 would have the x (leaving A and B) but he wants at least 500 not at most 500. So this makes B the correct answer.
X + y = 38
2x + 5y = 100
Where x is how many 2 pointers there were on the test and y how many 5 pinters there were
Elimination method:
2x + 2y = 76
2x + 5y = 100
2x - 2x + 2y - 5y = 76 - 100
-3y = - 24
y = 8
Apply it to the equation to get x
x + 8 = 38
x = 30
30 two pointers
8 five pointers
