Math Problem Statement

Find the x- and y-intercepts of the graph of minus, 3, x, plus, 2, y, equals, 20−3x+2y=20. State each answer as an integer or an improper fraction in simplest form.

Solution

To find the x- and y-intercepts of the equation 3x+2y=20-3x + 2y = 20, we'll follow these steps:

1. Find the x-intercept:

The x-intercept occurs when y=0y = 0. Substitute y=0y = 0 into the equation and solve for xx:

3x+2(0)=20-3x + 2(0) = 20

3x=20-3x = 20

x=203x = -\frac{20}{3}

So, the x-intercept is x=203x = -\frac{20}{3}.

2. Find the y-intercept:

The y-intercept occurs when x=0x = 0. Substitute x=0x = 0 into the equation and solve for yy:

3(0)+2y=20-3(0) + 2y = 20

2y=202y = 20

y=202=10y = \frac{20}{2} = 10

So, the y-intercept is y=10y = 10.

Final Answer:

  • The x-intercept is (203,0)\left(-\frac{20}{3}, 0\right).
  • The y-intercept is (0,10)\left(0, 10\right).
