Answer 1

`y = (1)/(8) x - 3`

Explanation:

Formula for straight lines:

`y = mx + b`

where m = slope, b = constant

Given:

y-intercept = -3 (0, -3)

m = ⅛

Substitute into formula to find b.

`- 3 = (1)/(8) (0) + b \\ - 3 = 0 + b \\ b = - 3`

Substitute b into original formula

`y = mx + b \\ y = (1)/(8) x + ( - 3) \\ y = (1)/(8) x - 3`
