Math Problem Statement
Identify the relationship between the lines given by the equations y = 3x - 5 and y = 3x + 2.
Solution
The image shows two linear equations:
These are equations of lines in slope-intercept form, , where:
- (the coefficient of ) is the slope.
- is the y-intercept.
Analysis of Each Equation
-
For :
- Slope () = 3
- Y-intercept () = -5
-
For :
- Slope () = 3
- Y-intercept () = 2
Observations
Both lines have the same slope of 3, meaning they are parallel. However, they have different y-intercepts, so they will never intersect. Parallel lines have no points in common, and thus there is no solution if we're trying to find an intersection point.
Would you like a detailed explanation on how to graph these lines or explore further properties?

Tip:
In a system of linear equations, if the lines are parallel, they have no solution (they are inconsistent).
