What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables. The solution is the point(s) where the equations intersect on a graph.

What does it mean to graph a system of equations?

Back

Graphing a system of equations involves plotting each equation on the same coordinate plane to find the point(s) where they intersect, representing the solution(s) to the system.

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is given by the equation y = mx + b, where m is the slope and b is the y-intercept.

How do you find the point of intersection of two lines?

Back

To find the point of intersection, solve the system of equations simultaneously, either by substitution or elimination.

What does the slope of a line represent in a real-world context?

Back

The slope represents the rate of change between the two variables in the context of the problem, such as cost per item or speed.

Front

What is the y-intercept of a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of y when x = 0.

How can you determine if a system of equations has no solution?

Back

A system has no solution if the lines are parallel, meaning they have the same slope but different y-intercepts.

Front

What does it mean if a system of equations has infinitely many solutions?

Back

A system has infinitely many solutions if the equations represent the same line, meaning they overlap completely.

How do you interpret the solution of a system of equations in a real-world scenario?

Back

The solution represents the values of the variables that satisfy all equations in the system, often corresponding to a specific situation or outcome.

What is the significance of the delivery fee in the fast food problem?

Back

The delivery fee is a fixed cost that affects the total cost of the meal, influencing the comparison between different options.
