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, 0.08) and (x2, y2) = (1, 10).
Slope a is .
Intercept is found from equation a%2Ax%5B1%5D%2Bb+=+y%5B1%5D, or 3.30666666666667%2A-2+%2Bb+=+6.69333333333333. From that,
intercept b is b=y%5B1%5D-a%2Ax%5B1%5D, or b=0.08-3.30666666666667%2A-2+=+6.69333333333333.

y=(3.30666666666667)x + (6.69333333333333)
