D:
use the graph of the line to answer the questions.
what is an equation of the line in point-slope form?
how can the point-slope form be written in function notation?

Point-slope form:

Slope-intercept form:

Step-by-step explanation:

You have points on that line at (-2, -1) and (1, 0). To find your slope using those points, use the slope formula.

Now that we have your slope, you can use your slope and one of your points to write an equation in point-slope form.

To put it in function notation, substitute y for f(x).
