Algebra 1 Semester 1 Review

Front

If y = -4/5x - 2, what is the value of x when y = -9?

Back

x = 35/4

Front

What is the range of the function shown?

Back

{-9, -4, -1}

Front

Which of the following is equivalent to 3x - 4y = 6?

Back

y = 3/4x - 3/2

Front

What is the function to find the total height of a building with n floors and an antenna?

Back

h(n) = 3.9n + 15.85

Front

What is the slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What does the y-intercept represent in a linear equation?

Back

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

Front

What is the definition of a function?

Back

A function is a relation that assigns exactly one output for each input.

Front

How do you determine the domain of a function?

Back

The domain is the set of all possible input values (x) for the function.

Front

What is the difference between independent and dependent variables?

Back

Independent variables are inputs (x), while dependent variables are outputs (y) that depend on the inputs.
