Question

Find the slope of the line that passes through the following points, (-2, 3) and (-1, -3)

Answer 1

\[gradient/slope=\frac{y2-y1}{x2-x1}\]
(-2,3) and (-1,-3)
(x1,y1) (x2,y2)

now substitute those values into the formula, tell me what you get.

Answer 2

-6/3 or -2

Answer 3

\[M = \frac{y2-y1}{x2-x1} = \frac{-3-3}{-1-(-2)}=\frac{-6}{1}=-6\]

Answer 4

you just need to be careful on the minus part.
x2 is -1 and x1 is -2
so when x2 - x1
-1 - (-2)
-1 + 2 = 1

Answer 5

y = mx + b

3 = -2m + b
-3 = -1m + b

b = 3 + 2m
b = m - 3

b = b
3 + 2m = m - 3
2m - m = -3 - 3
m = -6
