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=(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=(8-0)/(3-1)=(8)/(2)=4`

the slope is 4
