Answer:
y = -5/7x + 25
Explanation:
For slope-intercept form (y = mx + b), we need both the slope and the y-intercept.
We already have the y-intercept (0, 25), so we simply need to find the slope.
The slope formula is m= (y2 - y1) / (x2 - x1).
Thus, we can use the points (0,25) and (7,20) to get m = (20 - 25) / (7 - 0).
Solving gives us m = -5/7 and plugging this in gives us y = -5/7x + 25.
