Given the two points, we can plug them in the point-slope form formula and work it out to find the answer. (:
y-y1 = m(x-x1) <--- Point-slope formula
y-y1 = (y2-y1)/(x2-x1) x (x-x1) (We have to find slope as well)
y-(-1) = (2 - (-1))/((1/2)-(-3)) x (x-(-3))
y + 1 = 3 /(7/2) x (x+ 3)
y + 1 = 6/7 x (x+3)
y + 1 = 6(x+3) / 7
y + 1 = (6x + 18) /7
7(y+ 1) = 6x + 18
7y + 7 = 6x + 18
Now we can simplify this.
7y + 7 = 6x + 18
-7 -7
7y = 6x + 11
-6x -6x
-6x + 7y = 11 So, the answer is D. (:
