Math Problem Statement

2x+3y=12

Solution

The given equation is:

2x+3y=122x + 3y = 12

This is a linear equation in two variables, xx and yy. There are several things we can do with this equation, such as:

  1. Solving for one variable in terms of the other: We can express yy in terms of xx or xx in terms of yy.
  2. Finding intercepts: We can find the x-intercept and y-intercept by setting y=0y = 0 and x=0x = 0, respectively.
  3. Graphing the line: This equation can be represented as a straight line on the coordinate plane.

Let's solve for yy in terms of xx:

2x+3y=122x + 3y = 12 Subtract 2x2x from both sides: 3y=122x3y = 12 - 2x Now, divide by 3: y=122x3y = \frac{12 - 2x}{3} Simplifying: y=423xy = 4 - \frac{2}{3}x

This is the equation of the line in slope-intercept form y=mx+by = mx + b, where the slope m=23m = -\frac{2}{3} and the y-intercept is 44.

Would you like more details or a graphical representation of this line?

Here are 5 related questions:

  1. What is the x-intercept of this line?
  2. How do we graph this equation on a coordinate plane?
  3. Can we solve for xx in terms of yy?
  4. What is the slope of this line and what does it represent?
  5. How would this equation change if we added a constant to both sides?

Tip: To graph a line, find at least two points by setting one variable to 0 and solving for the other.
