Math Problem Statement
Point A is one vertex of triangle ABC. Point B is the x-intercept of 6x - 4y = -12 and point C is the y-intercept. What are points B and C? Sketch the triangle in the coordinate plane.
Solution
We are given the following information:
- Point A is at .
- Point B is the x-intercept of the line .
- Point C is the y-intercept of the same line.
Step 1: Find Point B (the x-intercept)
To find the x-intercept, set in the equation of the line :
So, Point B is .
Step 2: Find Point C (the y-intercept)
To find the y-intercept, set in the same equation:
So, Point C is .
Final Answer:
- Point B is .
- Point C is .

Here are five related questions for practice:
- What would the equation of the line look like if the intercepts were different?
- How would you calculate the midpoint between points B and C?
- What is the slope of the line through points B and C?
- How do the coordinates change if the line equation is modified to ?
- Can you find the area of triangle ABC using these points?
Tip: To find intercepts, always set the other variable to zero in the line equation.
