Intro to Linear Equations and Coordinates

The graph represents the allowance that Stefin and Daniel receive every week. "x" is the number of weeks, and "y" is the amount of money saved. What would the intersection point represent?

• They are starting with the same amount.

• 
  They have the same amount of money saved.

• They are starting with the same amount.

• 
  Both have reached their savings goal.

The two tables represent the values that correspond to a system of linear equations. What s the solution to this system of linear equations?

In a system of two linear equations, the solution is the (a)   where the lines intersect. If the two lines do not intersect, the solution is ​ (b)   . I know two lines in a system are parallel because their ​ (c)   are equal.

• point

• no solution

• y-intercept

• slopes

• infinite solutions

• x-intercepts

• one solution

An ordered pair that satisfies both equations in a system of linear equations is called a ​ (a)   to the system of equations.

• solution

• coordinate

• inconsistent

• input

Type the solution to the system of equations as an ordered pair, (x,y).
