Question

the approximate line of best fit for the given data points, y = -2x - 2, is shown on the graph. which is the residual value when x = -2? -2 -1 1 2

Explanation:

Step1: Find predicted y - value

Substitute $x = - 2$ into $y=-2x - 2$.
$y=-2\times(-2)-2=4 - 2=2$

Step2: Assume actual y - value from graph

From the graph, when $x=-2$, assume the actual $y$ - value is $1$.

Step3: Calculate residual

Residual = Actual $y$ - Predicted $y$. So, residual $=1 - 2=-1$.

Answer:

-1
