Graph the function y = -2x + . Tell whether or not each ordered pair lies on the line. Explain.

(0,1) (-5,3) (1,-1) (-2,5)

Graph it. Then you can see if the points are on the line.

To graph the function y = -2x + b, we need to plot several points that satisfy this equation and then connect them to form a straight line.

Let's start by choosing some x-values and substituting them into the equation to find their corresponding y-values.

Substituting x = 0 into the equation, we get y = -2(0) + b = 0 + b = b.
Therefore, the point (0, b) lies on the line.

Substituting x = -5 into the equation, we get y = -2(-5) + b = 10 + b.
So, the point (-5, 10 + b) lies on the line.

Substituting x = 1 into the equation, we get y = -2(1) + b = -2 + b.
Hence, the point (1, -2 + b) lies on the line.

Substituting x = -2 into the equation, we get y = -2(-2) + b = 4 + b.
Thus, the point (-2, 4 + b) lies on the line.

Now, we can plot these points on a coordinate plane and connect them to obtain the graph of the line.

The ordered pairs are:
(0, 1)
(-5, 3)
(1, -1)
(-2, 5)

Once you have plotted the points and connected them, you can see whether each ordered pair lies on the line by checking if they fall on the line you just drew. If the points fall exactly on the line, then they are on the line. Otherwise, they are not on the line.
