Question

Write the slope -intercept equation for the line that passes through (1,-9) and (3,-1)?
would my answer Y=4x-13

Answer 1

You are 100% correct, nice job

Answer 2

thanks!

Answer 3

You can verify your answer by plugging in each point

Checking (1,-9)

y=4x-13

-9=4(1)-13

-9=4-13

-9=-9 ... true

--------------------

Checking (3,-1)

y=4x-13

-1=4(3)-13

-1=12-13

-1=-1 ... true


So both points lie on the line which confirms the answer.
