Question

Which of the lines graphed has a slope of -1/2 and a y-intercept of 3?

Answer 1

Answerc

Explanation:

Answer 2

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`
