Graph the system of linear equations and then state how many solutions.

y=3x+5
y=3x+2

1 answer

To graph the system of equations given, we have:

  1. \( y = 3x + 5 \)
  2. \( y = 3x + 2 \)

Step 1: Graph the first equation

For the equation \( y = 3x + 5 \):

  • The y-intercept is \( 5 \), so the point \( (0, 5) \) is on the graph.
  • The slope is \( 3 \), which means for every 1 unit increase in \( x \), \( y \) increases by \( 3 \). So another point can be \( (1, 8) \) (since \( y = 3(1) + 5 = 8 \)).

Step 2: Graph the second equation

For the equation \( y = 3x + 2 \):

  • The y-intercept is \( 2 \), so the point \( (0, 2) \) is on the graph.
  • The slope is also \( 3 \), so another point can be \( (1, 5) \) (since \( y = 3(1) + 2 = 5 \)).

Step 3: Analyzing the lines

Both equations have the same slope of \( 3 \) but different y-intercepts. This means the lines are parallel to each other.

Step 4: Conclusion

Since the lines are parallel and will never intersect, the system of equations has no solutions.

So, the final statement is:

The system of equations has no solutions.
