Is the point 5,2 a solution of the equation y=2x+15

Mathematics

Answer:

No.

Step-by-step explanation:

To find out if a point is a solution, substitute "x" and "y" values from the point into the equation. Check if the equation is still balanced.

Point are written (x, y). So in (5,2), x = 5 and y = 2.

y = 2x + 15       Substitute for x and y

2 = 2(5) + 15    Simplify by multiplying

2 = 10 + 15       Simplify by adding

2 = 25

This is false. The equation is not balanced.

LS ≠ RS        Left side is not equal to right side.

Therefore (5,2) is not a solution on y=2x+15.
