Answer 1

slope bw two points (x1,y1)and (x2,y2) can be find by (y2-y1)/(x2-x1)

Answer 2

I got 4

Answer 3

3-(-1)/5-5=4

Answer 4

no its infinite because\[4/0= \infty\]

Answer 5

oh, ok

Answer 6

so slope is 90 degree

Answer 7

That's not any of the answers though

Answer 8

4/0 = infinity !

Answer 9

The slope is NOT 90º. The line makes a 90º angle with the x-axis. The denominator being zero suggests that the "slope" does not exist. That IS in the given answers.

Answer 10

undefined !

Answer 11

infinity or undefined.
