Find the equation of a line through the coordinate (3,−2) and parallel to the line represented y=12x−2. A y=12x−2 B y=−2x+4 C y=12x−72 D y=12x−52

Answer :

Answer:

Step-by-step explanation:

y=12x−2. parallel lines have the same slope 12

find b at point (3,-2)

y=12x+b

-2=12(3)+b

-2-36=b

b=-36

the equation has to be y=12x-38

when you input the point(3,-2)

-2=12(3)-38

-2=-2 correct

The equation of line is [tex]y=12x-38[/tex] which is parallel to given line [tex]y=12x-2[/tex]

Equation of parallel line given is, [tex]y=12x-2[/tex]

Compare above equation of line from [tex]y=mx+c[/tex]

Since, all parallel lines have same slope.

 Equation of line become,

                                             [tex]y=12x+c[/tex]

Since, line passing through point (3, -2).

               [tex]-2=12(3)+c\\\\c=-2-36=-38[/tex]

Hence, equation of line is [tex]y=12x-38[/tex] which is parallel to line [tex]y=12x-2[/tex]
