1. through: (0, -2) and (3, 4)

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) = (0, -2) and (x2, y2) = (3, 4).
Slope a is a+=+%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29+=+%284--2%29%2F%283-0%29+=+2.
Intercept is found from equation a%2Ax%5B1%5D%2Bb+=+y%5B1%5D, or 2%2A0+%2Bb+=+-2. From that,
intercept b is b=y%5B1%5D-a%2Ax%5B1%5D, or b=-2-2%2A0+=+-2.

y=(2)x + (-2)

Your graph:




your equation is:y=2x+-2


2. through (-3, 2) and (-2, 2)

intercept b is b=y%5B1%5D-a%2Ax%5B1%5D, or b=2-0%2A-3+=+2.

y=(0)x + (2)
