Question

Write an equation for the line parallel to the given line that contains C.
C(3,8); y= -4x+5

Answer 1

do u know that parallel lines have equal slopes

Answer 2

i am lost with this kind of problem...i know nothing about it

Answer 3

ok parallel lines have equal slope

Answer 4

got it?

Answer 5

Do you know the slope of the line given in your equation?

Answer 6

everything i posted was all the information i was given for the problem.
i looked on the internet at slope intercept equations and i though that maybe the slope in the equation was -4

Answer 7

@sauravshakya

Answer 8

Sorry for the late reply

Answer 9

Yep, u r very correct..... the slope of the line is -4

Answer 10

ok so the y-intercept of that equation is 5 then correct?

Answer 11

Now, the equation of the required line becomes,
y=-4x+c
and u need to find the value of the c using the given point C(3,8)

Answer 12

can u?

Answer 13

how do i do that??

Answer 14

substitue x=3 and y=8 in y=-4x+c and get the value of c

Answer 15

@ten is also very correct

Answer 16

can u? @smashinsam00

Answer 17

ok so c=20 then

Answer 18

YEP.

Answer 19

so, the required equation of the line becomes y=-4x+20
got it?

Answer 20

oh ok. i get it now. Thank You So Much @sauravshakya and @ten
