Which is a solution of the equation y = 4x + 3?
A-(5, 17)
B-(17,5)
C-(4, 19)
D-(4, 16)
To determine which option is a solution of the equation, we substitute the values of x and y from the option into the equation and check if they make the equation true.
Let's substitute the values of option A-(5, 17) into the equation:
y = 4x + 3
17 = 4(5) + 3
17 = 20 + 3
17 = 23
Since 17 is not equal to 23, option A-(5, 17) is not a solution of the equation.
Let's substitute the values of option B-(17,5) into the equation:
y = 4x + 3
5 = 4(17) + 3
5 = 68 + 3
5 = 71
Since 5 is not equal to 71, option B-(17,5) is not a solution of the equation.
Let's substitute the values of option C-(4, 19) into the equation:
y = 4x + 3
19 = 4(4) + 3
19 = 16 + 3
19 = 19
Since 19 is equal to 19, option C-(4, 19) is a solution of the equation.
Let's substitute the values of option D-(4, 16) into the equation:
y = 4x + 3
16 = 4(4) + 3
16 = 16 + 3
16 = 19
Since 16 is not equal to 19, option D-(4, 16) is not a solution of the equation.
Therefore, the correct solution of the equation y = 4x + 3 is option C-(4, 19).
