Answer by solver91311(24713) (Show Source): You can put this solution on YOUR website!

First use the point-slope form:

where

are the coordinates of the given point and

is the given slope.

Then solve your equation for

, which is to say arrange it in the form

also known as the slope-intercept form. Then the

-intercept is the point

where

is the constant term of the slope-intercept form. Be sure you report the

-intercept as an ordered pair with a zero

-coordinate. An intercept is a point that is only properly designated in

with an ordered pair. Expressing the

-intercept as a single number is an error.

There is an alternate process for determining the

-coordinate of the

-intercept. Using whatever equation form you like, substitute 0 for

. Then do the arithmetic required to determine the resulting value of

. That value will be

, the

-coordinate of the

-intercept. You still have to report an ordered pair as your answer.
