can someone please help me? Find the slope and y-intercept of the graph of the equation y=7x+9

OpenStudy (fwizbang):

If the equation looks like y = m*x +b, whatever multiplies x is the slope, and if you set x=0, what's left is the y-intercept.

OpenStudy (scarlettfarra2000):

Then the slope would be 7?

OpenStudy (fwizbang):

Yes

OpenStudy (scarlettfarra2000):

Okay then what's the y-intercept? @fwizbang

OpenStudy (fwizbang):

Look at the equation. Set x=0. What's y equal to?

OpenStudy (scarlettfarra2000):

9?

OpenStudy (fwizbang):

you got it!
