Question

I need this answered please

Answer 1

r = 2

Explanation:

The equation in the point slope form of the line is

y +2 =
`(-1)/(4)`(x -19) To change to the y intercept form of a line distribute the
`(-1)/(4)`

y + 2 =
`(-1)/(4)` x +
`(19)/(4)` Subtract 2 from both sides of the equation

y =
`(-1)/(4)`x +
`(11)/(4)` (
`(19)/(4)` -
`(8)/(4)`)

Now that we have the equation. The ask what is r when x is 3 (r is the y in the equation

y =
`(-1)/(4)` (
`(3)/(1)`) +
`(11)/(4)`

y =
`(-3)/(4)` +
`(11)/(4)`

y =
`(8)/(4)` = 2
