Question

Consider the equation and the following ordered pairs: (4, y) and (x, 1).y = 2x - 5Step 1 of 2: Compute the missing x and y values so that each ordered pair will satisfy the given equation.

Answer 1

Given the following equation:

$y=2x-5$

1. You know this value of "x" shown in the table:

$x=4$

Then, you can substitute it into the equation and evaluate, in order to find the corresponding y-value:

$\begin{gathered} y=2(4)-5 \\ y=8-5 \\ y=3 \end{gathered}$

2. To find the value of "x" when:

$y=1$

You have to substitute this value into the equation:

$1=2x-5$

And solve for "x":

$\begin{gathered} 1+5=2x \\ \\ \frac{6}{2}=x \\ \\ x=3 \end{gathered}$

Therefore, the answer is:
