In the ordered pair (a, – 12), the ordinate is 4 more than
two times the abscissa Find the value of a

Given: (x, y) = (a, -12)

A/q
y = 4 + 2x
-12 = 4 + 2a
2a = -12 - 4
2a = -16
a = -16/2
a = -8

In the ordered pair (a, – 12), the ordinate is 4 more than two times the abscissa. Find the value of a.
