Question

Find all values of y such that the distance between (3,y) and (-2,2) is 8.

Answer 1

y= -6

Explanation:

• Distance=Top-Bottom
• When I say Top-Bottom I mean you only deal with y values
• D=2-y
• Distance is given as 8
• Therefore 8=2-y
• 8-2=-y
• 6= -y
• we divide by -1 both side
• 6/-1 = -y/-1
• -6 = y
• Therefore y = -6
