Question

Please help What is the slope of the line through the points (–2, –1) and (8, –3)?

Answer 1

use the slope formula

m = (y2 - y1)/(x2 - x1)

Answer 2

You have (x1,y1) and (x2,y2)
The standard formula for slope, then, is :
m(slope) = (y2-y1)/(x2-x1)

Which you can find in your book.

Answer 3

Slope = (-3+1)/8+2= -2/10= -1/5
