Slope-Intercept Review

Front

Find the slope of the line that passes through the points (2, 4) and (6, 12)

Back

Slope = (y2 - y1) / (x2 - x1) = (12 - 4) / (6 - 2) = 8 / 4 = 2

Front

Find the slope of the line that passes through (10, 1) and (5, 2)

Back

Slope = (y2 - y1) / (x2 - x1) = (2 - 1) / (5 - 10) = 1 / -5 = -1/5

Front

Which equation best represents the relationship between x and y in the table shown?

Back

y = 5x + 5

Front

In slope intercept form, y = mx + b, what does m represent?

Back

m represents the slope of the line.

Front

What is the equation of the table?

Back

y = 3x + 1

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

How do you find the y-intercept in the equation y = mx + b?

Back

The y-intercept is the value of y when x = 0, represented by b.

Front

If the slope of a line is positive, what does that indicate about the line's direction?

Back

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

Front

If the slope of a line is negative, what does that indicate about the line's direction?

Back

A negative slope indicates that the line falls from left to right.
