Question 13

A system of equations consists of two of more linear equations. In Algebra I, we only explore systems with two equations. The solution of a system of equations is the solution that both equations share in common. Each linear equation has a set of solutions. For example, each point on a line is a solution for the equation of that line. If two lines intersect, the point of intersection is the solution that the two equations share in common. Thus, the intersecting point is the solution to the system of equations. The solution of a system of equations is _____.

Accepted Answer

The point where the two lines intersect

Answer

The y-intercept

Answer

The numerical value of the slope

Answer

The difference of the two slopes

Question 14

Accepted Answer

Dividing or multiplying both sides by the same value

Answer

Subtracting or adding the same value to both sides

Answer

Squaring both sides of the equation

Answer

Taking the square root of both sides of the equation
