Question

Help with this graph again??

Answer 1

y = (1/2)x + 4

Step-by-step explanation

The first step is to get the gradient of the line.

The two points in the line are; (0,4) and (-4, 2).

Gradient = (4 - 2)/(0 - -4)

= 2/4

= 1/2

To get the function we use one of the point (0,4) and a general point (x,y).

1/2 = (y - 4)/(x - 0)

1/2 = (y - 4)/x

1/2 x= y - 4

y - 4 = (1/2)x

y = (1/2)x + 4
