Question

What is the slope of the graph? Leave your answer as a reduced fraction.

Slope =

Identify the y-intercept. Write as a coordinate.

y-intercept =

Write an equation in slope-intercept form for the graph above.

y=

Answer 1

-¼ = Slope

[0, 2] = y-intercept

y = -¼x + 2

Explanation:

Your y-intercept is [0, 2] and your x-intercept is [8, 0] (not all the time your x-intercepts will be endpoints)]. Simply do rise\run until you hit another endpoint, starting from your y-intercept. As you can see, you go two blocks south, then eight blocks over east, since in this case, you are moving by increments of 2. If you were to recreate this graph in increments of 1, you would see that the simplification of -2\8, is -¼. That is why the rate of change is -¼. Do you understand?
