2x+3y=12 What is the x intercept and what is the y intercept

Solution

To find the xx-intercept and yy-intercept of the equation 2x+3y=122x + 3y = 12, we follow these steps:

1. Find the xx-intercept:

The xx-intercept occurs when y=0y = 0. Substituting y=0y = 0 into the equation: 2x+3(0)=12    2x=12    x=6.2x + 3(0) = 12 \implies 2x = 12 \implies x = 6. Thus, the xx-intercept is at (6,0)(6, 0).

2. Find the yy-intercept:

The yy-intercept occurs when x=0x = 0. Substituting x=0x = 0 into the equation: 2(0)+3y=12    3y=12    y=4.2(0) + 3y = 12 \implies 3y = 12 \implies y = 4. Thus, the yy-intercept is at (0,4)(0, 4).

Summary:

  • xx-intercept: (6,0)(6, 0)
  • yy-intercept: (0,4)(0, 4)
