4y = x - 24 what is the y intercept
sp2606 [1]

Answer:

In order to find the y-intercept you need to first get y by itself

To do so we need to divide y by 4, since we divide one side by four we need to divide the other side by 4 also

4y/4=x/4-24/4

y=1/4x-6

Now in the formula y=mx+b, you b is the y-intercept

In y=1/4x-6, the spot filled in for b is -6

Therefore; you y-intercept would be -6

-6

Hope this helps ;)
