See below

Explanation:

The slope of a line, #m#, is equal to:

#m=(y_2-y_1)/(x_2-x_1)#

where #(x_1,y_1)# and #(x_2,y_2)# are two points on the line.

#m=(-2-5)/(5-5)#

#m=-7/0# which is undefined. That simply means that the line that passes through these two points is vertical . Specifically, the line is:

#x=5#

The slope is undefined, or infinite.

Explanation:

Slope is found by #( y_1-y_2)/(x_1-x_2) = m # putting the values in gives

Slope = #{5 - (-2) }/( 5-5) = m#

Slope = # 7/0 = m#

Dividing by zero results in an infinite or undefined quality.

the slope of this line is straight up and has no defined mathematical value.

Slope = undefined

The slope is infinite or undefined.

Explanation:

We can answer this question by inspection, without having to use any formulae or calculations.

The given points both have the same #x#-values.

#(color(magenta)(5),5) and (color(magenta)(5),-2)#

On a graph this means that one point will lie directly above the other, meaning they will be joined by a VERTICAL line.

The slope of a vertical line is infinite or undefined.
