Math Problem Statement

Gina wrote the following equation on the board 6x + 2y = 12.

Part A: Which of the following points represent the x-intercept and y-intercept of the equation Gina wrote? Select all that apply. A.(6,0) B.(0,6) C.(0,2) D.(2,0) E.(0,0)

Solution

To find the intercepts of the equation 6x+2y=126x + 2y = 12, let's determine both the x-intercept and the y-intercept.

X-intercept:

The x-intercept occurs when y=0y = 0. Substitute y=0y = 0 into the equation: 6x+2(0)=12    6x=12    x=126=26x + 2(0) = 12 \implies 6x = 12 \implies x = \frac{12}{6} = 2 So, the x-intercept is (2,0)(2, 0).

Y-intercept:

The y-intercept occurs when x=0x = 0. Substitute x=0x = 0 into the equation: 6(0)+2y=12    2y=12    y=122=66(0) + 2y = 12 \implies 2y = 12 \implies y = \frac{12}{2} = 6 So, the y-intercept is (0,6)(0, 6).

Conclusion:

  • The x-intercept is (2,0)(2, 0), which corresponds to option D.
  • The y-intercept is (0,6)(0, 6), which corresponds to option B.

Thus, the correct answers are:

  • B. (0,6)(0, 6)
  • D. (2,0)(2, 0)

  2. Can an equation have multiple x- or y-intercepts?
  3. What happens if the equation has no intercepts?
  4. How do you find the slope of the equation 6x+2y=126x + 2y = 12?
  5. What is the significance of the intercepts in a real-world scenario?

Tip: Always remember that the x-intercept is where y=0y = 0 and the y-intercept is where x=0x = 0.
