Question

Here’s a graph of a linear function. Write the equation that describes that function. Express it in slope

Answer 1

y = (1/3)x +4

Explanation:

The line intercepts the y-axis at y=4. It has a "rise" of 1 unit for each "run" of 3 units, so its slope is rise/run = 1/3.

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

y = mx + b . . . . . where m is the slope and b is the y-intercept.

When we put the proper numbers in the equation, we have ...

y = (1/3)x + 4
