Which point below is a solution to the equation y = 2x - 5?
A. (2,0)
B. (1,-3)
C. (4,2)
D. (-1,-5)
To find a solution to the equation y = 2x - 5, we need to substitute the values of x and y from each option into the equation and see which one satisfies the equation.
Let's check each option:
A. (2,0)
y = 2(2) - 5 = 4 - 5 = -1 ✗ (not a solution)
B. (1,-3)
y = 2(1) - 5 = 2 - 5 = -3 ✓ (a solution)
C. (4,2)
y = 2(4) - 5 = 8 - 5 = 3 ✗ (not a solution)
D. (-1,-5)
y = 2(-1) - 5 = -2 - 5 = -7 ✗ (not a solution)
The point B. (1,-3) is the only option that is a solution to the equation y = 2x - 5.
