Answer:
The equation of line with slope -7 passing through (5,9) in point-slope form is:

Step-by-step explanation:
Given
Slope of line = m = -7
Point = (5,9)
The point slope form of equation is obtained from a point and slope. It is given by the equation:

We know that (x1,y1) = (5,9)
Putting the values we get

Hence,
The equation of line with slope -7 passing through (5,9) in point-slope form is:
