Question

Write the equation of the line that is parallel to the line y = 2x + 2 and passes through the point (5, 3).

y = 2x − 7

y = −x − 2

y = 2x − 2

y = −x − 7

Answer 1

State the slope which in this case is 2 according to y=mx+b

Answer 2

Then plug in y=mx+b and 2 as m and then plug in (5, 3) as x and y. Then solve for b.

Answer 3

so its either choice A or C

Answer 4

Correct. Because the slope has to be 2 because parallel lines have the same slope.

Answer 5

im pretty sure its A am i correct?

Answer 6

Well, lets see.
y=mx+b
we got 2 as m
and we have the coordinate (5,3)
x=5 y=3
Plug it in the formula.
y=mx+b
3=2(5)+b
3=10+b
subtract 10 from both sides.
-7=b


So now we got all neccesary items to rewrite this as another equation thats parallel to the previous equation.
We got the slope: 2
We got the b: -7
Plug it all in.
y=mx+b
y=2x-7

Answer 7

oh ok thanks alot!

Answer 8

Sure no problem :D
