From the question, it says in the c oordinate plane below, we should plot three poiints correspomding to the values x = -2, x = 0, and x = 2 in the equation y = -1 - 2x
recall, a linear function is a rule that assigns to each real number x the number y = mx + n, where m, n are real numbers.
The graph of a linear function is a straight line defined by two points of the function.
So, we have to plot the three points corresponding to the given values of x in the linear equation y = -1 - 2x. Therefore, we have to find the corresponding values of y by substituting the values of x in the given equation
For x = -2, we have y = -1 - 2(-2) = 3
For x = 0, we have y = -1 - 2(0) = -1
For x = 2, we have y = -1 - 2(2) = -5
Then the staight line that represents the linear function passes through the points A(-2, 3), B(0, -1) and C(2, -5)
