Answer
$y=-3.5-x$
Work Step by Step
Create a table that lists the values in the given set of ordered pairs. Order the table by the value of x.
$\underline{\ \ x\ \ }\ \ \ \ \underline{\ \ y\ \ }$
$-3.5\ \ \ \ \ \ 0$
$-3\ \ \ \ -0.5$
$-1\ \ \ \ -2.5$
$\ \ \ 0\ \ \ \ -3.5$
$\ \ \ 1\ \ \ \ -4.5$
$\ \ \ 2\ \ \ \ -5.5$
When x is 0, y is -3.5. -3.5 will be a constant in our equation and is the y-intercept.
Each time x increases by 1, y decreases by 1. Each time x decreases by 1, y increases by 1. This tells us that x will be multiplied by -1 in our equation.
$y=-3.5+(-1)x=-3.5-x$
Plot the points indicated by each ordered pair on a graph and join them with a straight line.
