@vinnv226 Help!!!

Answer 3

y2-y1/x2-x1 = m (gradient)
therefore m = -5.

Answer 4

To find the slope you're looking for the difference in y values over the difference in x values. You can pick any two points to work with, assuming this is a line. So lets take the first two points:
(-2, 2) and (-1, 3) So lets solve for the slope:
\[m=\frac{ \Delta y }{ \Delta x }=\frac{ 3-2 }{ -1--2 }=?\]

Answer 5

Well I managed to write the wrong point down, it's (-1,-3) not (-1,3)

Answer 6

-5 ? @vinnv226

Answer 7

Yep, thats right. If you'd like you can graph these points to check it, or use different points.
