1. Problem Description

We are given the equation 5x+4y=325x + 4y = 32 and are asked to find the slope and yy-intercept. The slope is given as 54-\frac{5}{4}, and the yy-intercept is given as (0,8)(0,8). We must check if these values are correct and provide simplified answers if needed.

2. Solution Steps

First, we solve the given equation for yy to get the slope-intercept form y=mx+by = mx + b, where mm is the slope and bb is the yy-intercept.
5x+4y=325x + 4y = 32
4y=5x+324y = -5x + 32
y=54x+324y = -\frac{5}{4}x + \frac{32}{4}
y=54x+8y = -\frac{5}{4}x + 8
From the equation y=54x+8y = -\frac{5}{4}x + 8, we see that the slope m=54m = -\frac{5}{4} and the yy-intercept is b=8b = 8.
Thus the slope is 54-\frac{5}{4}.
To write the yy-intercept as an ordered pair, we write (0,b)(0, b), so the yy-intercept is (0,8)(0, 8).

3. Final Answer

54-\frac{5}{4}
(0,8)(0, 8)
