Murrr4er [49]

Answer:

Parallel

Step-by-step explanation:

Parallel lines:

     The parallel lines have same slope.

y = 2x + 3

 Compare with slope y-intercept form of the line: y = mx +b

  m is slope and b is the y-intercept.

slope of this line = 2

y = 2x

Slope = 2

These lines have same slope. So, they are parallel.

What is the value of m that makes the equation true? 18m- 2+ 7m- 8= -60
sergij07 [2.7K]

Answer:

m = -2

Step-by-step explanation:

First, let's move all variables to one side of the equation. (Don't forget to change the signs when you move the numbers to the other side.)

18m + 7m = -60 + 2 + 8

Now we simplify to get this:

25m = -50

Now we divide -50 by 25 which gets us -2.

Therefore, m = -2

Hope this helps!
