Question

Tell if point (2,1) is a solution for the equation y = 2x - 5

Answer 1

Answer:

Point (2,1) is NOT a solution. Instead (2,-1) is a solution for the equation.

Step-by-step explanation:

To determine if the point (2,1) is a solution to the equation, substitute x=2 and solve for y.

$\begin{gathered} y=2(2)-5 \\ y=4-5 \\ y=-1 \end{gathered}$

Therefore, point (2,1) is NOT a solution. Instead (2,-1) is a solution for the equation.
