Math Problem Statement

Find the y-intercept and x-intercept of the line -5x + 6y = 9.

Solution

To solve the given problem, we need to find the x-intercept and y-intercept of the line represented by the equation:

5x+6y=9-5x + 6y = 9

Step 1: Find the y-intercept

The y-intercept occurs when x=0x = 0. Substituting x=0x = 0 into the equation:

5(0)+6y=9-5(0) + 6y = 9 6y=96y = 9 y=96=32y = \frac{9}{6} = \frac{3}{2}

So, the y-intercept is 32\frac{3}{2}.

Step 2: Find the x-intercept

The x-intercept occurs when y=0y = 0. Substituting y=0y = 0 into the equation:

5x+6(0)=9-5x + 6(0) = 9 5x=9-5x = 9 x=95=95x = \frac{9}{-5} = -\frac{9}{5}

So, the x-intercept is 95-\frac{9}{5}.

Final Answer:

  • y-intercept: 32\frac{3}{2}
  • x-intercept: 95-\frac{9}{5}

  1. How do you find the slope of the line 5x+6y=9-5x + 6y = 9?
  2. What is the slope-intercept form of the line 5x+6y=9-5x + 6y = 9?
  3. If the equation were 5x6y=95x - 6y = -9, what would the intercepts be?
  4. How do you graph the line using the intercepts 32\frac{3}{2} and 95-\frac{9}{5}?
  5. What is the distance from the origin to the y-intercept of this line?

Tip: Always substitute x=0x = 0 for the y-intercept and y=0y = 0 for the x-intercept directly into the equation!
