Question

The graph of a linear equation contains the points (4.1) and (-2,-11). Which point also lies on the graph?

Answer 1

(0, -7), (1, -5) .......

Explanation:

y = mx + b

m = (y-y') / (x-x') = (-11 - 1) / (-2 - 4) = -12 / -6 = 2

b = y - mx = 1 - 2 x 4 = -7

y = 2x -7

point 1 : x = 0 y = -7 (0, -7)

point 2: x = 1 y = -5 (1, -5)
