The answer is 3. $y = 2 x + 3$ $y=2x+3$ .

Explanation:

Substitute each value of $x$ $x$ into the equation and solve for $y$ $y$ . You will see that the values for $x$ $x$ and $y$ $y$ on the table will be determined by using the equation $y = 2 x + 3$ $y=2x+3$ .

$(x, y)$ $(color(red)x,color(blue)y)$
$y = 2 x + 3$ $color(blue)y=2color(red)x+3$

$(1, 5) \Rightarrow$ $(color(red)1,color(blue)5)rArr$

$y = 2 \cdot 1 + 3 = 2 + 3 = 5$ $color(blue)y=2*color(red)1 + 3=2+3=color(blue)5$

$(2, 7) \Rightarrow$ $(color(red)2,color(blue)7)rArr$

$y = 2 \cdot 2 + 3 = 4 + 3 = 7$ $color(blue)y=2*color(red)2+3=4+3=color(blue)7$

$(3, 9) r \Rightarrow$ $(color(red)3,color(blue)9)rrArr$

$y = 2 \cdot 3 + 3 = 6 + 3 = 9$ $color(blue)y=2*color(red)3 + 3=6+3=color(blue)9$

$(4, 11) \Rightarrow$ $(color(red)4,color(blue)11)rArr$

$y = 2 \cdot 4 + 3 = 8 + 3 = 11$ $color(blue)y=2*color(red)4+3=8+3=color(blue)11$
