Question

What is the equation of the blue line?

Answer 1

Answer: -1/2x + 2

Explanation:

first, we can find the y-intercept

as y begins two units above the origin, the y-intercept is 2

then, we can find the slope

as slope = rise over run, and the rise is -1 for every 2 units of run, the slope is -1/2

putting this together, y = -1/2x + 2
