The general equation of line with the slope "m" and passing points (a,b) is :
y - b = m (x -a)
In the given question:
Slope m = -2, passing points (a,b) = (4,-4)
Substitute the value of a = 4, b = -4 in the general equation of line
The equation with the slope -2 and passing points (4,-4) is 2x + y = 4
Answer : 2x + y = 4
You need to get "x" by itself on one side
Add positive eight on both sides---because its the opposite of negaitve
Divide -2 by -2
-2÷-2=1
