Math Problem Statement

5x-y=9

Solution

To solve the equation 5xy=95x - y = 9 for yy, let's isolate yy.

Step 1: Isolate yy

5xy=95x - y = 9 Subtract 5x5x from both sides: y=5x+9-y = -5x + 9 Multiply through by 1-1 to get yy on its own: y=5x9y = 5x - 9

So, the solution is: y=5x9y = 5x - 9

Here are 5 related questions to consider:

  1. How would you graph the equation 5xy=95x - y = 9?
  2. What is the slope of the line represented by y=5x9y = 5x - 9?
  3. Can you find the x- and y-intercepts of the line?
  4. How does changing the slope affect the graph of the line?
  5. What happens if we set x=0x = 0 in the equation?

Tip: The slope-intercept form y=mx+by = mx + b gives you a quick way to graph linear equations, where mm is the slope and bb is the y-intercept.
