Question

Determine the equation of a line that passes through a point P(-3,-2) and is parallel to line -x + 7y + 21 = 0.
​

Answer 1

Step-by-step explanation:

-x+7y+21 = 0

7y = x+21

y = x/7+3

here,

m1= 1/7

m2 = -7. (slope of parallel lines m1 =-1/m2)

equation of line;

y-y1 = m(x-x1)

y+2 = -7(x+3)

y +2 = -7x-21

y = -7x-23

I hope it helps you!!!!
