Front

What is the explicit equation for a linear function that passes through the point (0, 2) with a slope of 5?

Back

f(x) = 5x + 2

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

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

Front

What type of function adds the same number each time?

Back

Linear function

2

Front

What is the explicit equation for a linear function with a slope of -9 and a y-intercept of -2?

Back

f(x) = -9x - 2

Front

What does it mean for a function to be linear?

Back

A linear function has a constant rate of change and can be represented by a straight line on a graph.

Front

What is the general form of a linear equation?

Back

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

Front

How can you determine if a function is linear from a table of values?

Back

If the differences between consecutive y-values are constant for equal intervals of x, the function is linear.

Front

What is the slope of the line represented by the points (2, 3) and (4, 1)?

Back

Slope = (1 - 3) / (4 - 2) = -1
