Algebra 1, Semester 1 EXAM

Front

What is the formula for slope?

Back

Slope is defined as rise/run.

Front

What is the Vertical Line Test used for?

Back

The Vertical Line Test is used to determine if a graph represents a function.

Front

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

Back

A system has no solution if the lines are parallel and never intersect.

Front

Calculate f(-2) for the function f(x) = 3x + 1.

Back

f(-2) = 3(-2) + 1 = -6 + 1 = -5.

Front

What is the domain of the function represented by the graph?

Back

The domain is the set of all possible x-values for the function.

Front

What is a function?

Back

A function is a relation where each input has exactly one output.

Front

What is the range of a function?

Back

The range is the set of all possible output values (y-values) of a function.

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.

Front

What is the y-intercept of a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis (x=0).

Front

How do you find the x-intercept of a linear equation?

Back

Set y=0 in the equation and solve for x.
