Question

solve by graphing. \

$$\begin{cases} y = 2x + 3 \\\\ y = x + 1 \\end{cases}$$

(?, \square)

Explanation:

Step1: Find intersection by solving equations

Set the two equations equal: $2x + 3 = x + 1$
Subtract $x$ from both sides: $2x - x + 3 = 1$
Simplify: $x + 3 = 1$
Subtract 3: $x = 1 - 3 = -2$

Step2: Find y - value

Substitute $x = -2$ into $y = x + 1$: $y = -2 + 1 = -1$

Answer:

$(-2, -1)$
