Front

What letter represents the slope in the equation y = mx + b?

Back

m

Front

What is the y-intercept of the line graphed below?

Back

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

Front

In the equation y = -3x + 7, what is the y-intercept?

Back

7

Front

What is the slope in the equation y = 4x + 3?

Back

4

Front

Find the slope of the line that passes through the points (2, 3) and (4, 6).

Back

Slope = (y2 - y1) / (x2 - x1) = (6 - 3) / (4 - 2) = 3/2

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x.

Front

What is the formula for finding the slope between two points?

Back

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

Front

What is the y-intercept in the equation y = 2x - 5?

Back

-5

Front

How do you identify the slope from the equation y = mx + b?

Back

The slope is the coefficient of x, which is m.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line rises as it moves from left to right.
