Can someone me find out the slopes? you so much, much appreciated! (:

Part 1) The slope is equal to

Part 3) The slope is

Part 4) The slope is

Part 6) The slope is undefined

Part 8) The slope is

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

so

Part 1) Find the slope of the line that passes through the point (5,-5) and (9,-5)

Substitute in the formula

Part 3) Find the slope of the line that passes through the point (-2,9.5) and (4,5)

Substitute in the formula

Part 4) Find the slope of the line

Observing the graph the line passes through the point (-3,-4) and (4,1)

Substitute in the formula

Part 6) Find the slope of the line that passes through the point (-7,0) and (-7,-4)

Substitute in the formula

 ------> undefined

Part 8) Find the slope of the line that passes through the point (8,4) and (6,7)

Substitute in the formula

x coordinate is none

step-by-step explanation:
