Question

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 1

7x + y = -19 Option A

Step-by-step 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
