This equation is y = mx + b, where m is the slope.
If y = mx + b is ?// to y = - 3x + 7, that means they have the SAME SLOPE, so
y = - 3x + b. To calculate b, plug in the related value of (2,-4)
- 4 = - 3(2) + b
- 4 = - 6 + b and b = -4 + 6 = +2
Hence the final equation is y = -3x +2

Step-by-step explanation:
Answer:
It's D, reflects over the x-axis
Step-by-step explanation:
When you have a negative symbol outside the parentheses, all the y values are being multiplied by -1. This means that the points will have the same x, just that the y values will all be the opposite sign.
