The answer to this question is 4 (.2 x - 3.1 (x2 + 2 x)). Try using Wolfram for future questions - it's a sort-of calculator like website.
Answer:
y = x.
Step-by-step 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.
