Mr. brettler is hanging up a 5-foot tall rectangular welcome sign in the gym. he has drawn a sketch on a coordinate grid. he has the lower vertices of the sign at (9, –3) and (–6, –3). where would the upper vertices be on the grid?

The upper vertices are (9 , 2) and (-6 , 2)

Step-by-step explanation:

* Lets explain the information in the problem

- The welcome sign is a rectangle

- The height of it is 5 feet

- He has drawn a sketch on a coordinate grid

# On the sketch

- The lower vertices of the rectangle are (9 , -3) and (6 , -3)

- The lower vertices have the same y-coordinates

- The upper vertices will have the same y-coordinates which are greater

 than the y-coordinates of the lower vertices by 5 units, because the

 height of the sign is 5 feet

- The x-coordinates of the upper vertices have the same x-coordinates

 of the lower vertices because the sides of the rectangle perpendicular

 to each other

* Lets solve the problem

∵ The lower vertices are (9 , -3) and (-6 , -3)

∵ The x-coordinates of the lower vertices are 9 , -6

∴ The x-coordinates of upper vertices are 9 , -6

∵ The height of the sign is 5 units in the sketch

∴ We will add the y-coordinates of the lower vertices by 5

∵ The y- coordinates of the lower points are -3 and -3

∴ The y-coordinates of the upper vertices are -3 + 5 = 2 and -3 + 5 = 2

* Lets write the upper vertices

∵ The x-coordinates of upper vertices are 9 and -6

∵ The y-coordinates of upper vertices are 2 and 2

∴ The upper vertices are (9 , 2) and (-6 , 2)

Step-by-step explanation:

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
