Solved by pluggable solver: FIND EQUATION of straight line given 2 points
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, 6) and (x2, y2) = (-1, 2).
Slope a is a+=+%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29+=+%282-6%29%2F%28-1-1%29+=+2.
Intercept is found from equation a%2Ax%5B1%5D%2Bb+=+y%5B1%5D, or 2%2A1+%2Bb+=+4. From that,
intercept b is b=y%5B1%5D-a%2Ax%5B1%5D, or b=6-2%2A1+=+4.

y=(2)x + (4)
