Question

m = y2-y1=X2-X1Find the slope of the line that passesthrough these two points.(-1,-2) (-4,-1)Enter the correct symbol, + or --m = [?]

Answer 1

EXPLANATION

We can get the slope of the line that passes through the points by plugging in the numbers into the expression as shown as follows:

$m=\frac{y_2-y_1}{x_2-x_1}=\frac{-1-(-2)}{-4-(-1)}=\frac{1}{-3}=-\frac{1}{3}$

In conclusion, the slope is -1/3
