for finding the y intercept you have to let x=0 and then solve for y

put it in slope intercept form

to put it in slope intercept form you gotta add and subtract. remember you gotta when you're doing it do it to both sides.

sub in 0 for x 7x = 3y - 8 7(0) = 3y - 8 0 = 3y - 8 --- subtract 3y from both sides -3y = -8 -- now divide by -3 y = -8/-3 y = 8/3

The y-intercept is the point where the line crosses the y-axis. On the y-axis, all points have x-coordinate zero. The quickest way to do this is to replace x in the equation with zero, and solve for y. In other words, do what @mukushla suggest in the first response to this question.

you do not have to put it in y = mx + b form to find the y intercept,,,but you can. And if you do, the y intercept will be in the b position

no? how did you get that?

i multiplyed

that's not how it works.

x doesn't represent multiply in algebra, "x" is a variable.

oh i got it mixed up
