To verify if the points (-5, -49), (2, -22), and (3, 23) are solutions to the equation y = 9x - 4, we just need to plug the x and y values of the points into the equation and check if the equation is true.
For point (-5, -49), let x = -5 and y = -49:
-49 = 9*(-5) - 4
-49 = -45 - 4
-49 = -49
The equation holds true.
For point (2, -22), let x = 2 and y = -22:
-22 = 9*(2) - 4
-22 = 18 - 4
-22 = -22
The equation holds true.
For point (3, 23), let x = 3 and y = 23:
23 = 9*(3) - 4
23 = 27 - 4
23 = 23
The equation holds true.
Since all the given points satisfy the equation y = 9x - 4, they are all solutions to the equation.
Why is (-5, -49)(2,-22)(3,23) the solution to y=9x - 4
