Question

Write the equation of the line that is parallel to the line 3x − y = −3 and passes through the point (4, −2). ?? how do u do this?

Answer 1

well what is your slope?

Answer 2

Karate!!

Answer 3

GT!!

Answer 4

anyways jazlin what is your slope?

Answer 5

hpw would i find the slope?

Answer 6

To find slope, you need to re-arrange the equation into y=mx+b form where m is the slope.

Answer 7

i did that but i dont know how to completely slove it like this is what i put -2=m(4)+6

Answer 8

sorry i ment +b

Answer 9

3x-y=-3
=> y = 3x+3

So, slope = 3.

Answer 10

Now, you need to find the equation of the line parallel to this line and passing through point (4,-2).

Answer 11

Parallel lines have same slope. So, the new line must have a slope of 3. So, it must have the equation:

y = 3x + b. To find b, you should use the fact that this line passes through point (4,-2).

Answer 12

so the it would be -2=3(4)+b nd i have to solve it ?

Answer 13

does b=-6?

Answer 14

You got part of it.
-2 = 3*4+b
=> -2 - 12 = b = -14

So, new line is:
y = 3x-14

Answer 15

ohh thanks
