how do you go about finding yintercept and the slope for the equation 2y+3y=21

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 yintercept, 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
