Find the line's slope and a point on the line. y+5= 5(x-4)

slope:
point on the line:

x=4,y=5

so the points are 4 and 5

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

the correct is answer is a 9-sided polygon!
