Math Problem Statement

Find the x-intercept and y-intercept of the line 6x + 2y = -6.

Solution

To find the x-intercept and y-intercept of the given line equation:

6x+2y=66x + 2y = -6

Finding the x-intercept:

  • At the x-intercept, y = 0.
  • Substitute y=0y = 0 into the equation:

6x+2(0)=6    6x=66x + 2(0) = -6 \implies 6x = -6

  • Solve for xx:

x=66=1x = \frac{-6}{6} = -1

So, the x-intercept is (1,0)(-1, 0).

Finding the y-intercept:

  • At the y-intercept, x = 0.
  • Substitute x=0x = 0 into the equation:

6(0)+2y=6    2y=66(0) + 2y = -6 \implies 2y = -6

  • Solve for yy:

y=62=3y = \frac{-6}{2} = -3

So, the y-intercept is (0,3)(0, -3).

Summary:

  • x-intercept: (1,0)(-1, 0)
  • y-intercept: (0,3)(0, -3)

  2. How would the intercepts change if the equation was in slope-intercept form y=mx+by = mx + b?
  3. What is the geometric interpretation of the x- and y-intercepts on a graph?
  4. How do you graph a line using just the intercepts?
  5. How can you find intercepts when dealing with inequalities like 6x+2y66x + 2y \geq -6?

Tip: When finding intercepts, remember that each intercept occurs when the other variable equals zero!
