Question

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

A. 1/3
B. 1
C. 2
D. 4/3

Answer 1

-3-1 over -2-1 equals 4/3
the answer is D

Answer 2

Slope=
`(y_2-y_1)/(x_2-x_1)`

We are given two coordinates:
(x1,y1) and (x2,y2)

Plug given numbers into the formula:

`(1-(-3))/(1-(-2))`

Two "-"'s next to each other make a positive so we add:

`(1+3=4)/(1+2=3)`

Final answer: D.
Slope=
`(4)/(3)`
