Questions & Answers
Q: What are linear equations?
Linear equations are equations that result in straight lines when graphed due to the consistent relationship between the variables involved.
Q: How can linear equations be graphed?
Linear equations can be graphed by creating a table with values for x and determining the corresponding y values. Connecting the resulting points on the graph will form a straight line.
Q: What are the three conditions to recognize a linear equation?
The three conditions to recognize a linear equation are the presence of constants, variables not being squared or raised to higher powers, and variables not being multiplied together.
Q: Can linear equations have constants?
Yes, linear equations can have constants, such as in the equation y=2x+1. The constant value does not affect the fact that it is a linear equation.
Summary & Key Takeaways
