so I have to write an equation in slope intercept form for the line that satisfies each set of conditions. The problem has given me that the x intercept is 9 and the y intercept is -4.
The intercepts give you two points (9,0) and (0, -4). From those, you calculate a slope.
Then plug one of the points and the slope into the point slope form.
y-0 = (4/9)[x - (-4)]
9y = 4x + 16
