## anonymous one year ago Find the midpoint between two points on a number line if one of the points is at -7, and the other point is at 12. 5 9.5 2.5 -2

M = midpoint x_1 and x_2 = the two points (numbers) on the number line $M = \frac{ x_1 + x_2 }{ 2 }$

Do you understand the formula?

yes

So plug in the variables and then solve it. Tell me the answer once you get it so that I can confirm it with you.

ok

Let's check : $M = \frac{ x_1 + x_2 }{ 2 } = \frac{ -7 + 12 }{ 2 } = \frac{ 5 }{ 2 } = 2.5$

There might've been something wrong when you figured out 5. Did you catch your mistake?
