Answer:
The equation of line in the form of Ax + By = C is:
Step-by-step explanation:
We need to find the equation of line, having slope m = -4 and passes through point (-2,-9)
First we need to find slope and y-intercept of the line.
The slope is given i.e. m = -4
Now, we need to find the y-intercept
Using the point (-2,-9) and slope m = -4, y-intercept can be found using:
Now, the equation of required line having slope m = -4 and y-intercept b = -17 is:
Now writing in form of Ax + By = C
So, the equation of line in the form of Ax + By = C is: .
