Question 322924: Pls. help me understand how to do these math. Find the slope and the y-intercept.
1. y= 4x -9
2. y= -2x plus 3
3. -2x -8y =16

You can put this solution on YOUR website!
The slope intercept form of a line is y=mx%2Bb where m is the slope and b is the intercept.

.
1. m=4, b=-9
2. You fill in the answer on this one.
3. Sometimes you have to move terms around to get it into slope-intercept form,
-2x-8y=16
-8y=2x%2B16
y=-%281%2F4%29x-2
Again, read off the slope and intercept.
