Question

Increasing or decreasing?

slope?
y and x intercept?
other points the line goes through?
equation if the line?

Answer 1

Below in bold.

Explanation:

The line is rising to the right so it has an increasing slope.

The slope of the line is 4/8 = 1/2.

Reading from the graph the x intercept is (8, 0).

The y-intercept is (0, -4).

The line passes through the points (2, -3) and (6, -1).

The equation of the line is:

y = (1/2)x - 4.

Answer 2

slope = 1/2

The x-intercept is (8, 0). The y-intercept is (-4, 0).

(2, -3), (4, -2), (6, -1)

y = (1/2)x - 4

Explanation:

1)

slope = rise/run

Start at (0, -4) and go to (2, -3).

Start at (0, -4) and go 1 unit up. That is a rise of 1.

Now go 2 units right to arrive at (2, 3). That is a run of 2.

slope = rise/run = 1/2

2)

The line crosses the x-axis at (8, 0).

The x-intercept is (8, 0).

The line crosses the y-axis at (-4, 0).

The y-intercept is (-4, 0).

3)

Here are some points: (2, -3), (4, -2), (6, -1)

4)

y = mx + b

y = (1/2)x - 4
