Replace x with 18, solve the equation. If it equals -4 it’s a solution.
Y = -6(18) - -87
Y = -108 + 87
Y = -21
-21 does not equal -4 so (18,-4) is not a solution.
It depends if x is positive or negative and the same as in y
Eve makes twice as many free throws as she makes (3 x 2 = 6). So, if she misses 24 free throws, she makes twice that, 48.
Of course. I wish it will only go up !
First of all we have to find the slope
y₂-y₁
--------
x₂-x₁.
2 - (-2)
------------
0 - 7
4
---
-7
this is the slope
