Find an equation of the line with the slope m= -7 that passes through the the point (-2,-5) where the equation in the form Ax+By=C

ANSWER
7x + y = -19 Option A
EXPLANATION
Step 1:
y = mx + c where,
m = slope = -7,
y = -5,
x = -2 and
c = intercept = ?
-5 = -7(-2) +c
-5 = 14 + c
-5 - 14 = c
c = -19
Step 2: Insert the value of c
y = -7x - 19
add -7x to both sides
y + 7x = -7x - 19 + 7x
7x + y = - 19
