hahaWe are trying to find equation of form y=ax+b, where a is slope, and b is intercept, which passes through points (x1, y1) = (2, 5) and (x2, y2) = (0, -4).
Slope a is a+=+%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29+=+%28-4-5%29%2F%280-2%29+=+4.5.
Intercept is found from equation a%2Ax%5B1%5D%2Bb+=+y%5B1%5D, or 4.5%2A2+%2Bb+=+-4. From that,
intercept b is b=y%5B1%5D-a%2Ax%5B1%5D, or b=5-4.5%2A2+=+-4.

y=(4.5)x + (-4)
