Question

What is the slope of the line through (1,0) and (3,8)? Choose 1 answer: 1 4 B -4 с 1 4 D 4.

Answer 1

the formula to calculate the slope of a line is

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

we have the next points

(1,0)=(x1,y1)

(3,8)=(x2,y2)

Then we substitute the values

$m=\frac{8-0}{3-1}=\frac{8}{2}=4$

the slope is 4
