Question

Y= 5x – 4 when x = -2

Answer 1

`\begin{gathered} \text{When x = -2,} \\ y=-14 \end{gathered}`

Step-by-step explanation:

Given the equation:

`y=5x-4`

We want to obtain the value of y when x = -2.

Replace x with 2 in the equation

`\begin{gathered} y=5(-2)-4 \\ \\ =-10-4 \\ \\ =-14 \end{gathered}`

Therefore, when x = -2, then

`y=-14`
