Question

What is the slope of the line that passes through (3, -7) and (-1, 1)?

Answer 1

(3, -7) and (-1, 1)

To find slope of a line using 2 points

we use formula

`(y_2 - y_2)/(x_2-x_1)`

(3, -7) is (x1,y1) and (-1, 1) is (x2,y2)

Here x1= 3 and y1= -7

x2=-1 and y2=1

`(1- (-7))/(-1-3)`

`(8)/(-4)`=-2

slope of a line using 2 points (3, -7) and (-1, 1) is -2
