Introduction to Systems of Equations

What is the solution to a system of equations?

• The point where two lines intersect

• The point where two lines diverge

• The midpoint of two lines

• The starting point of a line

How do you find the y-intercept of a line?

• Find where the line crosses the x-axis

• Find where the line crosses the y-axis

• Calculate the slope

• Use the midpoint formula

Which of the following represents a system of equations?

In a system of equations, what does the intersection point represent?

• The y-intercept

• The midpoint of the lines

• The solution to both equations

• The slope of the lines

What is the first step when solving a system of equations by graphing?

• Substitute x for y

• Graph the first equation

• Find the slope

• Find the y-intercept

Which equation represents a line with a slope of 2 and a y-intercept of -3?

What does the slope of a line represent?

• The y-intercept

• The x-value of the line

• How quickly the line rises or falls

• The distance between two points

What does it mean if two lines in a system have the same slope and different y-intercepts?

• No solution, because they will always run parallel

• One solution

• Infinite solutions

• Cannot be determined

• Two solutions

• Infinite solutions

• No solution

• One solution
