Answer 2

Building a Graph for the Proportional Relationship

To build a graph for the proportional relationship given by the formula y = -0.5x + 5, we can use the provided formula to calculate the values of y for different x. Then, we can plot these points on a graph to visualize the relationship.

Let's calculate the values of y for a few different x values:

For x = 0: y = -0.5(0) + 5 = 5

For x = 2: y = -0.5(2) + 5 = 4

For x = 4: y = -0.5(4) + 5 = 3

For x = 6: y = -0.5(6) + 5 = 2

For x = 8: y = -0.5(8) + 5 = 1

Now, let's plot these points on a graph.

Plotting the Points on the Graph

We have the following points: - (0, 5) - (2, 4) - (4, 3) - (6, 2) - (8, 1)

Now, let's plot these points on a graph.

Determining if the Point M(-4, 7) Lies on the Graph

To determine if the point M(-4, 7) lies on the graph of the proportional relationship, we can substitute x = -4 into the given formula and check if it satisfies the equation.

For x = -4: y = -0.5(-4) + 5 = 7

So, the point M(-4, 7) does indeed lie on the graph of the proportional relationship.
