Algebra Unit 2 Slope

A number we can calculate using any two points on the line. To find it, divide the vertical distance between the points by the horizontal distance.

Answer explanation

The slope of a line is a number we can calculate using any two points on the line. To find the slope, divide the vertical distance between the points by the horizontal distance.

The slope of this line is 2 divided by 3 or 2/3.

A coordinate pair that makes both equations in the system true.

• solution to a system of equations

• expression

• constant of proportionality

• rate of change

Answer explanation

A coordinate pair that makes both equations in the system true is called a solution to a system of equations.

On the graph shown of the equations in a system, the solution is the point where the graphs intersect. In this system, the solution is (2,3).
