3(-1) + 5y = 17
add 3 to both sides
5y=20
divide by 5
y=4
Answer: Line of Symmetry means that there should be a line that makes both halfs of the shape, identical.
Step-by-step explanation:
If you draw a line on the girst parallelogram, then you see that the left side does not mirror the right side, thus not being symmetrical. The second shape that looks like a pentagon would by symmetrical and you wold draw the line right down the middle because then the left side would mirror the right side.
The other shape that would work would be the bottom left shape because if you draw a line of symmetry right down the middle of that shape, you can see that both sides are symmetrical and that the left side would mirror the right side.
Answer:
Step-by-step explanation:
y=mx + b is easier to solve for when you need to find slope intercept form. If you have your y and mx you can figure out what your b is.
