Answer:

The equation of the line is

[tex]y = \frac{1}{2} x - 4[/tex]

Step-by-step explanation:

Equation of a line is y = mx + c

where m is the gradient

c is the y intercept

Gradient = 1/2

Equation of the line using point ( 4 , -2) is

[tex]y + 2 = \frac{1}{2} (x - 4) \\ y + 2 = \frac{1}{2} x - 2 \\ y = \frac{1}{2} x - 2 - 2 \\ y = \frac{1}{2} x - 4[/tex]

Hope this helps you
