Answer 1

The equation of the line is y=-1/2x-3.5

Explanation:

Given the two points on the line, (1, -4) and (3, -5), find the slope of the line with the equation
`m=(y2-x2)/(y1-x1)`.

`m=(-5-(-4))/(3-1) =(-5+4)/(3-1) =(-1)/(2)`

After you find the slope of the line, substitute x and y with either point given to you. For me, I'll use point (1, -4) to solve for the y-intercept.

`-4=(-1)/(2) (1)+b`

`(1)/(2) -4=(-1)/(2) +(1)/(2) +b` add both sides by 1/2 so that b is alone

`(-7)/(2) =b`

You can rewrite -7/2 as -3.5.
