The co-ordinates are:
x-coordinate=2 | y-coordinate=1
x-coordinate=5 | y-coordinate=-8
x-coordinate=3 | y-coordinate=-2
x-coordinate=0 | y-coordinate=7
To match each x-coordinate with the corresponding y-coordinate, we can simply plug the x-coordinate into the equation y = -3x + 7 and solve for y.
x-coordinate = 2
y = -3(2) + 7
y = -6 + 7
y = 1
x-coordinate = 5
y = -3(5) + 7
y = -15 + 7
y = -8
x-coordinate = 3
y = -3(3) + 7
y = -9 + 7
y = -2
x-coordinate = 0
y = -3(0) + 7
y = 0 + 7
y = 7
Therefore, the correct matches are:
x-coordinate=2 | y-coordinate=1
x-coordinate=5 | y-coordinate=-8
x-coordinate=3 | y-coordinate=-2
x-coordinate=0 | y-coordinate=7
Question:
