Math Problem Statement

2x + y = 7

Solution

The given equation is:

2x+y=72x + y = 7

This is a linear equation in two variables, xx and yy.

Solving for yy:

We can isolate yy on one side of the equation by subtracting 2x2x from both sides:

y=72xy = 7 - 2x

Now, yy is expressed in terms of xx.

Graphical Interpretation:

This is the equation of a straight line in slope-intercept form y=mx+by = mx + b, where:

  • m=2m = -2 is the slope, indicating the line is sloping downwards.
  • b=7b = 7 is the y-intercept, meaning the line crosses the y-axis at y=7y = 7.

Do you have any further questions or would you like more details on graphing or solving?

Here are 5 related questions to consider:

  1. What is the slope of the line, and what does it represent?
  2. How do you find the x-intercept of this line?
  3. Can you determine the point where this line crosses the x-axis?
  4. How do we graph the equation step by step?
  5. Can we rewrite this equation in standard form?

Tip: Always check whether a line is increasing or decreasing by examining the sign of its slope.
