Final answer:
The coordinate pair (1, 1) is not a solution to the equation 5x - 3y = 8.
Step-by-step explanation:
To determine if the coordinate pair (1, 1) is a solution to the equation 5x - 3y = 8, we substitute the values of x and y into the equation and check if the equation holds true.
Let's substitute x=1 and y=1 into the equation:
5(1) - 3(1) = 8
5 - 3 = 8
2 = 8
The equation is not true, since 2 is not equal to 8. Therefore, the coordinate pair (1, 1) is not a solution to the equation.
