You can put this solution on YOUR website! Consider the line y=-3x+7
For each of the following points, is it located above, below or on the line?
Point
(-1,4)
(2,7)
---
Check how y relates to -3x+7 for each point:
Checking (-1,4)
4 R -3(-1)+4
4 R 3+4
4 < 7
So, (-1,4) is below the line
---------------------------
Checking (2,7)
7 R -3*2 + 7
7 R -6+7
7 R 1
7 > 1
So, (2,7) is above the line
