Question

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

Answer 1

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

Answer 2

Slope= $\frac{y_2-y_1}{x_2-x_1}$

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

Plug given numbers into the formula:
$\frac{1-(-3)}{1-(-2)}$

Two "-"'s next to each other make a positive so we add:
$\frac{1+3=4}{1+2=3}$

Final answer:  D.
Slope= $\frac{4}{3}$
