Question 618141: Write an equation in slope-intercept form for a line with a slope of -4 and y-intercepts of 9? In not sure where to start on the question I would appreciate it. Thank you!

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
