Question

Use the graph to write a linear function that relates y to I.

(2, 2)
(-2, 0)
(0, 1)
(-4, -1)

Answer 1

y = 1/2.x + 1 or... 2y = x + 2

Explanation:

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

m = (1 - 0)/(0 - (-2))

m = 1/2

y - y1 = m(x - x1):

y - 0 = 1/2(x - (-2))

2y = x + 2

y = 1/2.x + 1

Answer 2

htis is not a graph
