Question

Evaluate the following linear equation for the given values. y=-4x +2 when x is -3,-2, 0, 1

Answer 1

Given the linear equation:

`y=-4x+2`

To evaluate y for the given values of x, simply replace x with the given value and simplify.

Thus:

`\begin{gathered} \text{When }x=-3,y=-4(-3)+2=12+2=14 \\ \text{When }x=-2,y=-4(-2)+2=8+2=10 \\ \text{When }x=0,y=-4(0)+2=0+2=2 \\ \text{When }x=1,y=-4(1)+2=-4+2=-2 \end{gathered}`

Therefore:

• When x=-3, y=14

,

• When x=-2, y=10

,

• When x=0, y=2

,

• When x=1, y=-2
