Find an equation of the line with the given slope that passes through the given point. write the equation in the form ax plus by equals upper ax+by=c. m equals seven fourths comma left parenthesis 8 comma negative 9 right parenthesis

The given points in the problem is (7/4, 0) and (8,-9) 

Then write the equation in point-slope form.this would be m = (-9 - 0)/(8 - 7) = -9

Then form this in the format: y = mx + b

then solve for "b":
-9 = -9*8 + bb = 8

The equation in slope form is:y = -9x + 8
