Question

What is the equation of the line in standard form that passes through the point (–1, 4) and is parallel to the line y = 2x – 3?

OPTIONS:
A) x – 2y = 6
B) x + 2y = 6
C) 2x – y = –6
D) 2x + y = –6

Answer 1

do u know what is the slope of the line y=2x-3 ?

Answer 2

2

Answer 3

right

Answer 4

So, (1,4) is the point we given.
TO eb parrallel, the slopes have to be the same.
Using the form y=mx+b, where m is the slope, we can say the new equation has to be y=2x+b
so using the (1,4), we go 4=2(1)+b, solve for b
b=2
so the equation of the line is y=2x+2

Answer 5

but thats not one of my options

Answer 6

Woops, I missed a negative sign

Answer 7

b=6, so y=2x+6

Answer 8

okay thanks

Answer 9

but wich option is it?

Answer 10

Do you understand the process though?

Answer 11

Just rearrange the equation.

Answer 12

is it D?
