Answer:

  y = 3x +4

Step-by-step explanation:

The equation for the parallel line will have the same x- and y-coefficients, but a different constant. You can put the given point values into the equation to see what the constant needs to be:

  y = 3x + b

  10 = 3·2 + b . . . . . . substitute x=2, y=10

  4 = b . . . . . . . . . . . . subtract 6

The equation of the line is ...

  y = 3x +4

Help me out with this problem please!!and (please tell me how you got the answer.)
Sati [7]
The answers are that the number can equal -4 or 1. 

You can find this by setting the number equal to x.

x^2 (The square of a number) + 3x (three times a number) = 4

x^2 + 3x = 4 ---> subtract 4 from each side
x^2 + 3x - 4 = 0

Then you can factor this to find the answers

(x - 4)(x + 1) = 0

Set both equal to 0 and solve.
