Question

Here's a graph of a linear function. Write the

equation that describes that function.
Express it in slope-intercept form.​

Answer 1

y = 3/4x +2

Explanation:

The line crosses the y-axis at 2, so that is the y-intercept. The line appears to have a rise of 3 for a run of 4, so rise/run = slope = 3/4.

The slope-intercept form of the equation of a line is ...

y = (slope)x + (y-intercept)

y = 3/4x + 2
