Why would 2x + 3y = 7 not be a solution to 5, -1
Because it graphs intersect at 5, -1
Because it doesn’t graph at 5, -1
2x + 3y = 7 cannot be a solution to the point (5, -1) because when you substitute x=5 and y=-1 into the equation, it does not satisfy the equation.
2(5) + 3(-1) = 10 - 3 = 7
This shows that the point (5, -1) is not a solution to the equation 2x + 3y = 7.
