Which equation represents the graphed function?

y = -2x + 3

Step-by-step explanation:

The three is the y-intercept, so when x=0, y will equal 3. (0,3)

The slope is negative (-2x), because the minus is present infront of x. So the line's going down.

And we can confirm that it's the function

y = -2x + 3 by letting one point in the line from the graph enter the function.

For example (1,1)

1 = -2x + 3. (let y = 1.)

1 = -2(1) + 3 (let x = 1)

1 = 1

so we can see when we let 1 = -2(1) + 3 it equals the y value on the line.

A) a scatterplot with an odd number of points in which the correct regression line passes directly through 0 of the points.

Think about it, if there is an odd number, and the line touches none of them, then there must be at least one more point on one side of the line than there is on the other side.
