Semester 1 Review

Front

What type of function does a straight line represent?

Back

Linear function.

Front

What is the value of f(6) if f(6) = 2?

Back

f(6) = 2.

Front

How do you calculate the rate of change between two points?

Back

Rate of change = (change in y) / (change in x).

Front

What type of function does a graph that increases rapidly represent?

Back

Exponential function.

Front

What is the slope of a line?

Back

The slope is the ratio of the rise (change in y) to the run (change in x).

Front

What is the y-intercept of a graph?

Back

The y-intercept is the point where the graph crosses the y-axis.

Front

What is the formula for a linear function?

Back

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

Front

What does a slope of 1/2 indicate?

Back

For every 2 units you move right, the line moves up 1 unit.

Front

What is the significance of the y-intercept in a linear equation?

Back

It indicates the starting value of y when x = 0.

Front

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

Back

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