Question

How do you find the y intercept

Answer 1

So if you have an equation in the form y=mx+b, b= the y intercept so just convert any equation to that form

exg
6x+8y=8
subtract 6x from both sdies
8y=-6x+8
divide both sides by 8
y=-6/8x+1
y intercept=1
they y intercept is where the line crosses the y axis, or when x is equal to zero so it is the same as setting x to zero and solving for y
6x+8y=8
if x=0
0+8y=8
divide both sides by 8
y=1
y intercept is still 1

Answer 2

You can find the y-intercept by looking at the graph and seeing which point crosses the y axis. This point will always have an x coordinate of zero. This is another way to find the y-intercept, if you know the equation, the y-intercept is the solution to the equation when x = 0.
