You can put this solution on YOUR website! The x-intercept can be written as point (12,0) and the y-intercept can be written as (0,4).
If you use the slope-intercept form for a line (), then you must find , which is the slope, and b, which is the y-intercept.
To find , use the formula .
Plug the points in: =
Now that you have the value of and you have the value of given to you in the question (4), you can plug the numbers into the slope-intercept formula for the equation of your line.
That line graphed would look like:
Hope this helps!
