Linear Equations in Two Variables
What are linear equations in two variables?
Linear equations in two variables are algebraic expressions involving two variables, typically denoted as x and y, with no variable raised to a power greater than 1.
How do you graph linear equations in two variables?
To graph a linear equation in two variables, ax + by = c, you can rearrange it into slope-intercept form, y=mx + b, where m is the slope and b is the y-intercept, then plot points using the slope and intercept.
What methods can be used to solve systems of linear equations in two variables?
Systems of linear equations in two variables can be solved using methods such as substitution, elimination, and graphing.
What is the significance of the slope in a linear equation?
The slope of a linear equation represents the rate of change of the dependent variable (y) with respect to the independent variable (x). It indicates the steepness of the line on the graph.
What does it mean when two linear equations in two variables are parallel?
If two linear equations in two variables have the same slope but different y-intercepts, they are parallel lines, and the system of equations has no solution. This indicates that the lines never intersect on the coordinate plane.
