Question

Is the point (5,7) a valid solution to y>-2x+9

Answer 1

Yes, the point (5,7) is a valid solution to y>-2x+9. When we substitute x=5 and y=7 into the inequality, we get 7 > -2(5) + 9, which simplifies to 7 > -10 + 9. This is true because 7 > -1. Therefore, the point (5,7) satisfies the inequality.
