Question

Complete each order pair so that it is a solution of the given linear equation.
y=1/3x-9; (15, ), ( ,-6)
The 1st order pair is (15, )
The 2nd order pair is ( ,-6)
Help please

Answer 1

Each ordered pair is (x,y). Determine the coordinates by substitution.

for (15,y):
y=1/3 * 15 - 9
y=-4

for (x,-6):
-6=1/3x -9
1/3x=3
x=9
