Question

complete the equation describing how x and y are related.

x	y
0	3
1	8
2	13
3	18
4	23

$y = 5x + ?$
enter the number that belongs in the green box.

Explanation:

Step1: Use x=0, y=3 to solve for intercept

Substitute $x=0$, $y=3$ into $y=5x+b$:
$3 = 5(0) + b$

Step2: Calculate the intercept value

Simplify to find $b$:
$b = 3$

Step3: Verify with another pair (e.g., x=1, y=8)

Substitute $x=1$, $b=3$ into the equation:
$y = 5(1) + 3 = 8$, which matches the table.

Answer:

3
