y = 5x -7
Values that are solutions are the ones in which the value of x and y when substituted give equal values in the equation
For example, (1,-2) where x = 1 and y =-2, substituting with this values yields
-2 = 5(1) -7
-2 =5-7
-2 = -2
so option A is a solution. other points that are solutions are ; (3,8) and (0,-7)
However, we are asked to find points that are not solutions to the equation, therefore we will instead lookout for points where the value of x and y when substituted are not equal
such options include ; (1,2), (0,1) and (-1.-2)
For example, using (-1,-2) where x = -1 and y =-2 as our points yield
-2= 5(-1) -7
-2 = -5-7
-2 is not equal to -12
so ( -1, -2) is not a solution to the equation
Checking with (0,1)
1 = 5(0) -7
1 is not equal to -7
so (0,1) is not a solution to the equation
Checking (-1,-2)
-2 = 5(-1) -7
-2 is not eqaul to -12
so (-1,-2) is not a solution too
