Answer:
y = (-1/2)x + 4
Explanation:
Moving from (0, 4) to (2, 3), we see x increasing by 2 from 0 to 2 and y decreasing by 1 from 4 to 3.
Thus, the slope of this line is m = rise / run = -1/2.
Starting with y = mx + b, we substitute 0 for x, 4 for y and -1/2 for b, obtaining:
4 = (-1/2)(0) + b. Therefore, b = 4, and the desired equation is:
y = (-1/2)x + 4
