Question

y = 4x - 2

x	y
1
4
5
6

Explanation:

Step1: Substitute x=1 into the equation

We have the equation \( y = 4x - 2 \). When \( x = 1 \), we substitute \( x \) into the equation: \( y = 4\times1 - 2 \). Calculating this, \( 4\times1 = 4 \), then \( 4 - 2 = 2 \). So when \( x = 1 \), \( y = 2 \).

Step2: Substitute x=4 into the equation

When \( x = 4 \), substitute into \( y = 4x - 2 \): \( y = 4\times4 - 2 \). \( 4\times4 = 16 \), then \( 16 - 2 = 14 \). So when \( x = 4 \), \( y = 14 \).

Step3: Substitute x=5 into the equation

When \( x = 5 \), substitute into \( y = 4x - 2 \): \( y = 4\times5 - 2 \). \( 4\times5 = 20 \), then \( 20 - 2 = 18 \). So when \( x = 5 \), \( y = 18 \).

Step4: Substitute x=6 into the equation

When \( x = 6 \), substitute into \( y = 4x - 2 \): \( y = 4\times6 - 2 \). \( 4\times6 = 24 \), then \( 24 - 2 = 22 \). So when \( x = 6 \), \( y = 22 \).

Answer:

For \( x = 1 \), \( y = 2 \); for \( x = 4 \), \( y = 14 \); for \( x = 5 \), \( y = 18 \); for \( x = 6 \), \( y = 22 \)
