Calculating Slope from Tables Quiz

What does the slope of a line represent?

• Product of x and y coordinates

• Change in y over change in x

• Sum of x and y coordinates

• Difference between highest and lowest y values

How do you calculate the slope between two points (x1, y1) and (x2, y2)?

• (y2 - y1) / (x2 - x1)

• (x2 + x1) / (y2 + y1)

• (x2 - x1) / (y2 - y1)

• (y2 + y1) / (x2 + x1)

If the slope is negative, what does it indicate about the line?

• The line is decreasing

• The line is increasing

• The line is horizontal

• The line is vertical
