Question

Determine wether each ordered pair is a solution of the given equation.

17. y=3x-5; (0,5), (-1,-8)

18. y=-2x+7; (1,5),(-2,3)

19. -6x+5y=-6; (1,0), (2,6/5)

20. 5x-3y=9; (0,3), (12/5,-1)

21. y=2x^2; (1,2), (3,18)

22. y=2|x|; (-1,2), (0,2)

23. y=^3; (2,8), (3,9)

24. y=x^4; (-1,1), (2,16)

25. y=√x+2; (1,3), (4,4)

26. y=3√x-4; (1,-3), (8,6)

Answer 1

17. No, 18. Yes, 19. Yes, 20. No, 21. Yes, 22. No, 23. No, 24. Yes, 25. Yes, 26. No...to get these, just plug the x-value in for x and y value in for y for each of the points. If one of the points does not work, they are not points on the line.
