Answer: The answer would be C

Step-by-step explanation:

The two lines intersect on (20, 6) so that means that the charging rates were the same when on that point. And since it is asking for how many minutes they charge at the same amount, that would make it 20.

Write the equation of a line parallel to y=2x+2 that passes through the point (-1, -7)
alexira [117]

Answer: y=2x-5

Step-by-step explanation:

To find the line that is parallel to y=2x+2, we know the slope must be 2. Parallel lines NEVER touch. That tells us that the slope must be 2. Now, all we have to do is to plug in the point to find the y-intercept.

-7=2(-1)+b            [multiply]

-7=-2+b                [add both sides by 2]

b=-5

With the y-intercept, we can find the parallel line.

y=2x-5
