Front

Which equation matches the graph with a slope of 1/4 and y-intercept of 2?

Back

y = 1/4 x + 2

Front

Define a function.

Back

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

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 it mean if a line has an undefined slope?

Back

The line is vertical and does not have a defined slope.

Front

What is the y-intercept of the equation y = 3x + 5?

Back

The y-intercept is 5.
