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 is a solution for the equation y=4x+3, we substitute the given values for x and y into the equation and check if they satisfy it.
Let's substitute the values from each option:
A. (5,17)
y = 4(5) + 3
y = 20 + 3
y = 23
The equation is not satisfied, so this option is not correct.
B. (17,5)
y = 4(17) + 3
y = 68 + 3
y = 71
The equation is not satisfied, so this option is not correct.
C. (4,19)
y = 4(4) + 3
y = 16 + 3
y = 19
The equation is satisfied, so this option is correct.
D. (4,16)
y = 4(4) + 3
y = 16 + 3
y = 19
The equation is not satisfied, so this option is not correct.
The solution to the equation y=4x+3 is (4,19).
Therefore, the correct option is C. (4,19).
