find the slope of the line that goes through the following points (0,-4),(1,-3),(2,-2),(3,-1)

a.) -1
b.)1
c.) -4
d.) -7

1 answer

slope between the first two points
= (-3+4)/(1-0) = 1

checking for a second pair, 1st and last
slope = (-1+4)/(3-0) = 1

I will let you check that the other 4 combinations yield the same slope of 1
