Question

What is the slope of the line that passes through the points (-3, -3)and (-9, 5) ?

Answer 1

y = -
`(4)/(3)`x-7

Explanation:

y=mx+b where m = the slope and b = the y intercept

the slope = change over y/change over x = (5-(-3))/(-9-(-3))=(5+3)/(-9+3)=8/(-6)=4/(-3)

y=-4/3x+b

plug in one of the points (it can be either)

-3=-4/3(-3)+b

-3=4+b

b=-7

y=-4/3x-7
