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) = (1, 7) and (x2, y2) = (0, 0).
Slope a is a+=+%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29+=+%280-7%29%2F%280-1%29+=+7.
Intercept is found from equation a%2Ax%5B1%5D%2Bb+=+y%5B1%5D, or 7%2A1+%2Bb+=+0. From that,
intercept b is b=y%5B1%5D-a%2Ax%5B1%5D, or b=7-7%2A1+=+0.

y=(7)x + (0)
