Question

Does the coordinate (-2,5) land on the linear equation y = 2x + 9 ?yesnomaybe

Answer 1

Answer:

Yes

Explanation:

The coordinate (-2,5) corresponds to the point (x, y).

This means that:

x= -2 and y=5

To check if the coordinate land on the equation y=2x+9, calculate the value of y when x= -2

$\begin{gathered} \text{When x=-2} \\ y=2(-2)+9 \\ =-4+9 \\ =5 \end{gathered}$

Therefore, the coordinate (-2,5) land on the linear equation y = 2x + 9.
