Question

Slope intercept form of (1,1) (2,-2)

Answer 1

Explanation:

(1,1) (2,-2)

Y2 = -2 , y1 = 1 , x2 = 2 , x1 = 1

Slope m = (y2 - y1)/(x2 - x1)

m = (-2 - 1)/(2 - 1)

m = -3/1

m = -3

And the equation of line

y - y1 = m(x - x1)

y - 1 = -3(x - 1)

y - 1 = -3x + 3

y = -3x + 3 + 1

y = -3x + 4
