x=45y

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

y=mx+b

Combine 45 and y.

x=4y5

Rewrite the equation as 4y5=x.

4y5=x

Multiply both sides of the equation by 54.

54⋅4y5=54x

Simplify both sides of the equation.

Simplify 54⋅4y5.

Cancel the common factor of 5.

Cancel the common factor.

54⋅4y5=54x

Rewrite the expression.

14⋅(4y)=54x

14⋅(4y)=54x

Cancel the common factor of 4.

Factor 4 out of 4y.

14⋅(4(y))=54x

Cancel the common factor.

14⋅(4y)=54x

Rewrite the expression.

y=54x

y=54x

y=54x

Combine 54 and x.

y=5×4

y=5×4

Rewrite in slope-intercept form.

y=54x

y=54x

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

b=0
