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 = 1/2x + 3

Explanation:

As per graph, using the points (-6, 0) and (0, 3) we determine that:

• the y-intercept is 3 and
• the slope is m = (3-0)/(0 - (-6)) = /3/6 = 1/2

So the equation is:

• y = mx + b
• y = 1/2x + 3
