Question

Write the equation of a line in slope-intercept form from the graph below.

tytyty

Answer 1

y = x.

Explanation:

From the graph we see that the line passes through the origin (0, 0) and the point (8,8), so the slope is (8-0) / (8-0) = 1.

The y intercept is at (0.0).

y =- mx + c is the slope intercept form so m = 1 and c = 0 and the answer is

y = 1x + 0

y = x.
