Math 8- Slope and Slope Intercept Form Review

Front

What is the definition of slope?

Back

Slope is a measure of the steepness of a line, calculated as the rise over run between two points on the line.

Front

What does a positive slope indicate?

Back

A positive slope indicates that as the x-value increases, the y-value also increases, resulting in an upward slant from left to right.

Front

What does a negative slope indicate?

Back

A negative slope indicates that as the x-value increases, the y-value decreases, resulting in a downward slant from left to right.

Front

What does a zero slope indicate?

Back

A zero slope indicates a horizontal line where the y-value remains constant regardless of the x-value.

Front

What does an undefined slope indicate?

Back

An undefined slope indicates a vertical line where the x-value remains constant regardless of the y-value.

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is given by the equation y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you identify the y-intercept from an equation?

Back

The y-intercept can be identified as the value of b in the slope-intercept form y = mx + b.

Front

How do you graph the equation y = 3/4x?

Back

Begin at (0,0), put a point. Go up 3 units and right 4 units to place another point.

Front

What is the y-intercept of the equation y = 1/3x - 3?

Back

The y-intercept is -3.

Front

If m = 2 and b = 5, what is the slope-intercept equation?

Back

The equation is y = 2x + 5.
