Which is a solution to the equation y = 2x – 5? A.(3, 11) B.(2, 1) C.(1, –3) D.(5, –5)
Dvinal [7]
The correct answer is C. (1, -3).

In the brackets, the first number refers to x, and the second to y (like when you write coordinates).

So we can check what is y ineach of the options and compare whether both of the sided of the equasion are equal:
A. 2x-5=-1, should be 11, false
B. 2x-5=4-9=-5, should be 1, false
C. 2x-5=2-5=-3, should be -3, correct
D. 2x-5=10-5=5, should be -5, false
