Which of the lines below has an undefined slope?

The correct option is B.

Step-by-step explanation:

The slope of a line is calculated as

The slope of line is undefined if there is no change in the values of x. It is possible only in the case of vertical line.

Graph B represents a vertical line. So the slope of the line in graph B is

The slope of line B is undefined, therefore the correct option is B.

8y^50

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
