Video Slope Formula

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

• Slope equals y1 minus y2 over x1 minus x2

• Slope equals x2 minus x1 over y2 minus y1

• Slope equals y2 minus y1 over x2 minus x1

• Slope equals x1 minus x2 over y1 minus y2

What is true about the slopes of parallel lines?

• They are different

• They are the same

• They are perpendicular

• They intersect at one point

What should you do first when calculating the slope of a line through two points?

• Calculate the midpoint

• Write out the given points

• Find the y-intercept

• Draw the line on a graph

Why is it important to use parentheses when calculating slope?

• To simplify the calculation

• To make the equation look neat

• To avoid mistakes with negative numbers

• To ensure the slope is always positive
