Is (1,9) a solution to this system of equations? y = 5x + 4 y = 2x + 7 Choices: (A)yes (B)no

First Equation Analysis: We have the first equation: y = 5x + 4 Does the point (1, 9) satisfy the first equation? y = 5x + 4 9 = 5(1) + 4 9 = 5 + 4 9 = 9 Yes, the point (1, 9) satisfies the first equation y = 5x + 4.Second Equation Analysis: We have the second equation: y = 2x + 7 Does the point (1, 9) satisfy the second equation? y = 2x + 7 9 = 2(1) + 7 9 = 2 + 7 9 = 9 Yes, the point (1, 9) satisfies the second equation y = 2x + 7.Solution Verification: We found: (1, 9) satisfies the equation y = 5x + 4. (1, 9) satisfies the equation y = 2x + 7. Is (1,9) a solution to the system of equations? y = 5x + 4 y = 2x + 7 Both equations are true when (x, y) = (1, 9). Yes, (1,9) is a solution to the system of equations.
