Answer: A.(0,-3) Step-by-step: To determine if a point is a solution to the equation, we can substitute the x and y values of the point into the equation and see if it holds true. A. (0,-3) - Substitute x = 0 and y = -3 into the equation:0 - 6(-3) = 180 + 18 = 1818 = 18- The equation holds true, so point (0,-3) is a solution. B. (6,-2) - Substitute x = 6 and y = -2 into the equation:6 - 6(-2) = 186 + 12 = 1818 = 18- The equation holds true, so point (6,-2) is a solution. C. (1,2) - Substitute x = 1 and y = 2 into the equation:1 - 6(2) = 181 - 12 = 18-11 = 18- The equation does not hold true, so point (1,2) is not a solution. Key Knowledge: - A solution to an equation is a set of values for the variables that make the equation true. Tips: - When checking if a point is a solution, it is important to substitute the values of the variables correctly into the equation.- If the equation holds true after substitution, then the point is a solution. If not, then the point is not a solution.
