Math Problem Statement

3x-2y=10

1.Find the x- and y-intercept(s) of the graph, if any exist.

Solution

Let's solve for the x- and y-intercepts of the equation 3x2y=103x - 2y = 10.

Step 1: Finding the x-intercept

The x-intercept occurs when y=0y = 0. To find it, substitute y=0y = 0 into the equation and solve for xx.

3x2(0)=103x - 2(0) = 10

This simplifies to:

3x=103x = 10

Now solve for xx:

x=103x = \frac{10}{3}

So, the x-intercept is (103,0)\left(\frac{10}{3}, 0\right).

Step 2: Finding the y-intercept

The y-intercept occurs when x=0x = 0. To find it, substitute x=0x = 0 into the equation and solve for yy.

3(0)2y=103(0) - 2y = 10

This simplifies to:

2y=10-2y = 10

Now solve for yy:

y=102=5y = \frac{-10}{2} = -5

So, the y-intercept is (0,5)(0, -5).

Conclusion

  • x-intercept: (103,0)\left(\frac{10}{3}, 0\right)
  • y-intercept: (0,5)(0, -5)

  2. How can you graph the line 3x2y=103x - 2y = 10 using the intercepts?
  3. What is the slope of the line 3x2y=103x - 2y = 10?
  4. How do you find the slope-intercept form of a line from its general form like 3x2y=103x - 2y = 10?
  5. What happens to the intercepts if the equation involves a negative constant on the right-hand side?

Tip: To find intercepts, always set one variable to 0 and solve for the other. It makes the process quicker and easier!
