Question

The slope of the line below is -1. write the point-slope equation of the line using the coordinates of the labeled point.​

Answer 1

Explanation:

-9 = -1 x 4

-9 = -4

=5

y = -x + 5

Answer 2

y+9=-1(x-4)

Explanation:

Point Slope Form is:

`y-y_1=m(x-x_1)`

When:

'm' is the slope.

`(x_1,y_1)` is the coordinate.

We are given the slope of -1 and the coordinate of (4,-9).

So:

`m=-1\\x_1=4\\y_1=-9`

Using the information and replacing the values we get:

`y+9=-1(x-4)`

So, the line equation in point slope form should be: y+9=-1(x-4)
