Question

Choose the equation of the line passing through the point (2, -4) and parallel to y = 3x - 6.

A. y = 3x - 10

B. y = 3x - 6

C. y = 3x - 2

D. y = 3x - 12

Answer 1

since the line is parallel to given line..their slopes are equal..can you find the slope from the given line??

Answer 2

@abhi7 is it d?

Answer 3

are u just guessing or u have calculated??

Answer 4

honestly just guesssing, i don't know where to even begin on this.

Answer 5

compare the given equation y=3x-6 to y=mx+c..what is m here??

Answer 6

3?

Answer 7

yes here m is the slope of the line y=3x-6..since the line we need to find is parallel to this line its slope will also be 3

Answer 8

now using point slope form y=mx+c..since (2,-4) passes through the line and m=3..use (x,y)=(2,-4) and m=3 in y=mx+c to find c..try to find c now

Answer 9

y= 3 2 + -4
y= 6 + -4
y=2
so its y = 3x - 2?

Answer 10

you have put -4 in c..-4 should be put in y

Answer 11

find the value of c.. we have given (x,y)..try one more time

Answer 12

- 4 = 3.2 + c?
is that the right equation?

Answer 13

yes now find c

Answer 14

-4 = 6
-6 -6
c= -10?
oh my god im sorry... thanks for the patience.

Answer 15

correct..after finding c..you have slope(m) and y-intercept(c) of the given line..substitute these values in y=mx+c and you have the required equation..

Answer 16

Thank you so much!(:
