Exploring Slope Concepts and Applications

The video tutorial reviews the concept of slope, explaining its types: positive, negative, zero, and undefined. It demonstrates how to find slope using a graph and ordered pairs, and discusses the characteristics of parallel and perpendicular lines, including their slopes and negative reciprocals.

What type of slope is represented by a line going up from left to right?

• Positive

• Negative

• Zero

• Undefined

If a line is going straight up and down, what is its slope?

• Undefined

• Positive

• Zero

• Negative

What is the formula for calculating slope from a graph?

• Rise over run

• y2 - y1 over x2 - x1

• x2 - x1 over y2 - y1

• Run over rise

If the rise is 4 and the run is 5, what is the slope?

• 4/5

• 5/4

• 1/2

• 2/1

What is the formula for calculating slope from ordered pairs?

• Run over rise

• y2 - y1 over x2 - x1

• Rise over run

• x2 - x1 over y2 - y1

Given points (6, -1) and (-2, 5), what is the slope?

• -4/3

• 3/4

• 4/3

• -3/4

What is true about parallel lines?

• They have the same slope

• They form right angles

• They have different slopes

• They intersect

What is the negative reciprocal of 3/4?

• -4/3

• 4/3

• -3/4

• 3/4

If line AB has a slope of 2/5 and line CD has a slope of -5/2, what is true about these lines?

• They are parallel

• They are perpendicular

• They intersect at an acute angle

• They are neither parallel nor perpendicular

Given points (3, 3) and (-1, 0), what is the slope?

• 4/3

• -3/4

• -4/3

• 3/4
