Answer: (1, 11) and (-1, -5), OPTION C
We are given the equation
y = 8x + 3
This implies that the value of y is a function of x
Firstly, we need to test the options
For (1, 11)
From the point given, let x = 1 and y = 11
Substitute the value of x and y in the above equation
Since, y = 8x + 3
11 = 8(1) + 3
11 = 8 + 3
11 = 11
This implies that (1, 11) satisfied the equation y = 8x + 3
For (-1, -5)
Let x = -1 and y = -5
-5 = 8(-1) + 3
-5 = -8 + 3
-5 = -5
The point (-1, -5) satisfies the equation y = 8x + 3
Hence, the answer is (1, 11) and (-1, -5)
