Y-y1= m(x1-x2)
using this formula
the answer is d
because slope has to remain the same if its parallel
I think the answer is 2 and -15. Because 2 times - 15 is -30 and 2 and -15 can be added to -1.
Hi there! The answer is x = -1
Let's solve this equation step by step!

First collect terms.

Subtract (1/2)x from both sides.

Subtract 3 from both sides.

And finally divide by -1 3/4
A) Reflection because each vertex and the images are the same distance from the y-axis
