Asked by o.

how do you go about finding y-intercept and the slope for the equation -2y+3y=-21
Answered by drwls
One of the y's in your equation should probably be an x. Please verify your typing.

Rewrite your equation (after correcting it) into y = mx + b form.

m will be the slope and b will be the y-intercept, where the straight line crosses the y axis.

-2y+3y = -21
y(-2+3)= -21
y(1)= -21
y = -21 + (-1)
y = -21 - 1
y = -22

miyako's answer is incorrect. If both terms on the left contain a y, then y = -21. You would have a horizontal line with zero slope.

I still believe one of your x's should be a y

move the x1,y1,x2, and y2 sliders back and forth.which sliders affect the rise?
