A design engineer is mapping out a new neighborhood with parallel streets. If one street passes through (4, 7) and (3, 3), what
is the equation for a parallel street that passes through (−2,4) y = 4x + 12, y = 4x − 14 y equals negative one-fourth times x minus 1 y equals negative one-fourth times x plus 7 halvesh
You want to be finding out what two factors (where one of them is a perfect square) has the produce of 63. It seems like 9 x 7 (9 is the perfect square) works.
The square root of 9 is 3 so we can just have (which just means 3 times the square root of 7).
