Question

Write an equation in slope intercept form of the line passing through each pair of points

(0, 5) and (3 -4)

Answer 1

Subtract your Y’s from each other:
-4 - 5 = -9
Subtract your X’s from each other:
3-0=3

-9/3=-3 that is your slope

Take a point let’s take (3,-4)

-4=-3(3)+b
-4=-9+b
How to get to -4 with -9 that is 5.
Answer: y=3x+5
( the 3 comes from the previous work)
