graphing linear equations
vectored instruction
graph the equation by filling in the chart.
equation: y = 3x + 1
x | y
0 | 1
1 | ?
2 |
3 |
4 |
(and a coordinate grid)

Explanation:

Step1: Substitute x = 1 into the equation

We have the equation \( y = 3x + 1 \). When \( x = 1 \), we substitute \( x \) with 1 in the equation.
\( y = 3(1) + 1 \)

Step2: Calculate the value of y

First, calculate \( 3(1) = 3 \), then add 1. So \( y = 3 + 1 = 4 \).

Answer:

4
