Like terms are terms that have the same variables raised to the same powers.To add like terms, add their coefficients.
ST has a midpoint at M(3, 7). Point S is at (3, 5). Find the coordinates of point T.
T=(3,9)
Since you know the midpoint of the line segment, you can use the midpoint formula to find the missing endpoint. Plug in the midpoint M(3, 7) and plug in S(3, 5) for (x1, y1). Point T will be at (x2, y2).

What are proofs?
A geometric proof is a deduction reached using known facts such as axioms, postulates, lemmas, etc. with a series of logical statements.
What are dilations?
A dilation is a function from a metric space into itself that satisfies the identity for all points, where is the distance from to and is some positive real number
