1. Problem Description

The problem requires us to convert the given linear equation 5xy=85x - y = 8 to slope-intercept form, and then identify the slope and y-intercept of the line.

2. Solution Steps

Step 1: Convert the given equation to slope-intercept form.
The slope-intercept form of a linear equation is given by:
y=mx+by = mx + b
where mm is the slope and bb is the y-intercept.
Starting with the given equation:
5xy=85x - y = 8
Subtract 5x5x from both sides:
y=5x+8-y = -5x + 8
Multiply both sides by 1-1:
y=5x8y = 5x - 8
Therefore, the equation in slope-intercept form is y=5x8y = 5x - 8.
Step 2: Identify the slope.
Comparing the equation y=5x8y = 5x - 8 to the slope-intercept form y=mx+by = mx + b, we can see that the slope m=5m = 5.
Step 3: Identify the y-intercept.
The y-intercept is the value of yy when x=0x = 0. In the equation y=5x8y = 5x - 8, the y-intercept b=8b = -8. As an ordered pair, the y-intercept is (0,8)(0, -8).

3. Final Answer

Slope-intercept form: y=5x8y = 5x - 8
Slope: m=5m = 5
Y-intercept: (0,8)(0, -8)
