Algebra 1 Semester Test-1

Front

What is the slope of the equation y = mx + b?

Back

The slope (m) represents the rate of change of y with respect to x.

Front

What does it mean if two lines are parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

What is the solution to a system of equations?

Back

The solution is the point(s) where the graphs of the equations intersect.

Front

What does it mean if a system of equations has no solution?

Back

It means the lines are parallel and do not intersect.

Front

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

Back

It means the equations represent the same line.

Front

How do you solve a system of equations using substitution?

Back

You solve one equation for one variable and substitute that expression into the other equation.

Front

What is the elimination method in solving systems of equations?

Back

The elimination method involves adding or subtracting equations to eliminate one variable.

Front

What is the y-intercept of the equation y = mx + b?

Back

The y-intercept (b) is the point where the line crosses the y-axis.

Front

How do you find the x-intercept of an equation?

Back

Set y to 0 and solve for x.

Front

What is the difference between a linear equation and a non-linear equation?

Back

A linear equation graphs to a straight line, while a non-linear equation graphs to a curve.
