tentukan gradien p ( -7,5) dan q ( 6,2) tlong dbntu ya!!!!!!! pleaseeeeee

m = (y2 - y1)/(x2 - x1)
m = (2 - 5)/(6 + 7)
m = -3/13

(y-5) / (2-5) = (x-(-7) /(6-(-7))
y-5 / -3 = (x + 7) / 13
y- 5 = -3(x + 7) / 13
y - 5 = (-3x -21) /13
13 y - 65 = -3x -21
13y = -3x + 44
y = -3/13 x +44/13
gradiennya = -3/13
