Answer:

The answer is image 3.

Explanation:

The equation for the line will be y = (-1/2)x + 3 so the gradient is negative and you will have to find the x-intercept and y-intercept.

x-intercept :

$let \: y = 0$

0 = - (1)/(2) x + 3

(1)/(2) x = 3

x = 3 / (1)/(2)

x = 6

y-intercept :

$let \: x = 0$

y = - (1)/(2) (0) + 3

y = 3
