2. (3,-2), (6,1)

The equation of the straight line passing through the points (x1, y1) and (x2, y2),

y - y1 = (y2 - y1)/(x2 - x1)* (x -x1)

y - -2 = (1 - -2)/(6 - -2)* (x - 3)

y + 2 = 3/8 (x - 3)

y = mx + b

y + 2 = 3/8 (x - 3)

solve for y

8y + 16 = 3(x -3)

8y + 16 = 3x - 9

y = 3/8x - 25/8

check my math

you try number 1
