Question

To model the equation y=3x-4 I made the table shown which value did incorrectly record other table
X. Y
-1. -4
0. -2
2. -2
5. 11

Answer 1

Let's check each of the \( x \) values in your table and see what the corresponding \( y \) values should be according to the equation \( y = 3x - 4 \).

1. **For \( x = -1 \)**:
\[
y = 3(-1) - 4 = -3 - 4 = -7
\]
(You recorded \( -4 \), which is incorrect.)

2. **For \( x = 0 \)**:
\[
y = 3(0) - 4 = 0 - 4 = -4
\]
(You recorded \( -2 \), which is incorrect.)

3. **For \( x = 2 \)**:
\[
y = 3(2) - 4 = 6 - 4 = 2
\]
(You recorded \( -2 \), which is incorrect.)

4. **For \( x = 5 \)**:
\[
y = 3(5) - 4 = 15 - 4 = 11
\]
(You recorded \( 11 \), which is correct.)

### Summary of Corrections
- For \( x = -1\): should be \( y = -7 \)
- For \( x = 0\): should be \( y = -4 \)
- For \( x = 2\): should be \( y = 2 \)
- For \( x = 5\): correctly recorded as \( y = 11 \)

In conclusion, the incorrectly recorded values in your table are for \( x = -1 \), \( x = 0 \), and \( x = 2 \).
