I need help with this problem

M = Now let's substitute in our given values -2 2) = 2 Find 12 and y2 We will now set up two equations to solve for our two unknowns of :2 and y2 - -5 +12) / 2 -2 We will first want to multiply by 2 on both sides and will get -5 + $2 - -4 Adding 5 to both sides we get 2 This is the a coordinate of point B. Now we will set up the equation to solve for y/2 7 +y2) /2 = 2 We will first want to multiply by 2 on both sides and will get 7 +y2 32 This is the y-coordinate of point B. The coordinates of point B are
