Answer:
y+9=-1(x-4)
Step-by-step explanation:
Point Slope Form is:
[tex]y-y_1=m(x-x_1)[/tex]
When:
'm' is the slope.
[tex](x_1,y_1)[/tex] is the coordinate.
We are given the slope of -1 and the coordinate of (4,-9).
So:
[tex]m=-1\\x_1=4\\y_1=-9[/tex]
Using the information and replacing the values we get:
[tex]y+9=-1(x-4)[/tex]
So, the line equation in point slope form should be: y+9=-1(x-4)
