Math Problem Statement

Find the x-intercept and y-intercept of the graph of the equation 5x - 3y = 15.

Solution

The image contains a problem asking to find the x-intercept and y-intercept of the graph for the equation 5x3y=155x - 3y = 15.

Steps to Find the Intercepts:

1. Find the x-intercept:

The x-intercept occurs when y=0y = 0. To find it:

  • Set y=0y = 0 in the equation 5x3y=155x - 3y = 15: 5x3(0)=155x - 3(0) = 15 5x=155x = 15 x=155=3x = \frac{15}{5} = 3 So, the x-intercept is (3,0)(3, 0).

2. Find the y-intercept:

The y-intercept occurs when x=0x = 0. To find it:

  • Set x=0x = 0 in the equation 5x3y=155x - 3y = 15: 5(0)3y=155(0) - 3y = 15 3y=15-3y = 15 y=153=5y = \frac{15}{-3} = -5 So, the y-intercept is (0,5)(0, -5).

Final Answer:

  • x-intercept: (3,0)(3, 0)
  • y-intercept: (0,5)(0, -5)

  1. How do the x- and y-intercepts relate to the graph of a line?
  2. What is the slope of the line represented by the equation?
  3. How would you graph this equation using the intercepts?
  4. What would happen to the intercepts if the equation were 5x+3y=155x + 3y = 15?
  5. Can you interpret the equation of a line in general form and explain its components?

Tip: Always remember that intercepts give you two key points to graph a linear equation quickly.
