Could someone please check my work.

what is the slope of the line that passes through the given points?(2,12( and (6,11)

-1/4 (my choice)

1/4

4

-4

My work:

11-12/6-2=-1/4

what is the slope of the line that passes through the given points?

undefined( my choice)

0

-2/3

-3/2

My work;

-1-(-1)/-3-6=0/9

Write an equation in slope-intercept form what are the slope and y-intercept?

y=9/10x+9/10;slope;9/10;yintercept;9/10

y=9/10x-9/10;slope;9/10;y-intercept;9/10

y=-9/10x+9/10;slope;9/10;yintercept;9/10

y=9/10x-9/10;slope9/10;y-intercept;-9/10

This one I definitely need help with.

First question is correct

for the second, you don't state the points but from "My work", I am guessing the points were

(-3,-1) and (6,-1)

so the slope is (-1 + 1)/(6 + 3) = 0/9 = 0 , not undefined

for the last one: corrections in bold

y=9/10x+9/10;slope;9/10;yintercept;9/10

y=9/10x-9/10;slope;9/10;y-intercept;**-9/10**

y=-9/10x+9/10;slope;**-9/10**;yintercept;9/10

y=9/10x-9/10;slope9/10;y-intercept;-9/10
