Slope-intercept form looks like 
. Strictly speaking, your question is incorrectly stated. The slope value is a number, so -4 is perfectly fine for the value of the slope, however, an intercept is a point on the plane (or in more general terms a point in 
-space), and in this 
example, must be designated by an ordered pair rather than a scalar number. What I have to assume is meant is that the 
-coordinate of the -intercept is 9. Of course, the 
-coordinate of the -intercept is always zero, so your intercept point is )
.
in the slope-intercept form is the slope and 
in the slope-intercept form is the -coordinate of the -intercept.
All you have to do is insert the numbers in place of the formula placeholders and

My calculator said it, I believe it, that settles it
