-4x+8y=0

The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.

y=mx+b

Add 4x to both sides of the equation.

8y=4x

Divide each term by 8 and simplify.

Divide each term in 8y=4x by 8.

8y8=4×8

Cancel the common factor of 8.

Cancel the common factor.

8y8=4×8

Divide y by 1.

y=4×8

y=4×8

Cancel the common factor of 4 and 8.

Factor 4 out of 4x.

y=4(x)8

Cancel the common factors.

Factor 4 out of 8.

y=4×4⋅2

Cancel the common factor.

y=4×4⋅2

Rewrite the expression.

y=x2

y=x2

y=x2

y=x2

Rewrite in slope-intercept form.

y=12x

y=12x

Using the slope-intercept form, the y-intercept is 0.

b=0
