Math Problem Statement

Find the x- and y-intercepts of the graph of 8, x, plus, 2, y, equals, 348x+2y=34. State each answer as an integer or an improper fraction in simplest form.

Solution

The equation provided is:

8x+2y=348x + 2y = 34

To find the intercepts, we'll evaluate the equation for both xx-intercepts and yy-intercepts separately.

1. Finding the xx-intercept:

For the xx-intercept, set y=0y = 0 in the equation and solve for xx:

8x+2(0)=348x + 2(0) = 34 8x=348x = 34 x=348=174x = \frac{34}{8} = \frac{17}{4}

Thus, the xx-intercept is x=174x = \frac{17}{4}, and the coordinate point is: (174,0)\left(\frac{17}{4}, 0\right)

2. Finding the yy-intercept:

For the yy-intercept, set x=0x = 0 in the equation and solve for yy:

8(0)+2y=348(0) + 2y = 34 2y=342y = 34 y=342=17y = \frac{34}{2} = 17

Thus, the yy-intercept is y=17y = 17, and the coordinate point is: (0,17)(0, 17)

Summary:

  • The xx-intercept is (174,0)\left(\frac{17}{4}, 0\right).
  • The yy-intercept is (0,17)(0, 17).
