Question

Write an equation in point slope form through the point (3,-1) with a slope of 2

what is the answer to this?

Answer 1

`y+1 = 2 (x -3)`

Explanation:

Point slope form is

`y - y_(1)=m(x-x_(1))`

The points you have are (3, -1). The 3 is
`x_(1)` and the -1 is
`y_(1)`

The slope, m, is 2.

Plugin the numbers for the variables.

`y - -1 = 2 (x -3)\\y + 1 = 2 (x - 3)`
