Answer:
x<6
Step-by-step explanation:
x+1 < 7
Subtract 1 from each side
x+1-1<7-1
x <6
Well, you would use factorization for this, which would be MORE than 54 different codes! :D
The slope for the first one would be:
y2-y1/x2-x1, so replace those with the coordinates and you'll get:
-3-1/-7-(-7) => -4/0 so I guess the slope is zero
the slope for the second one would be:
-3-(-3)/5-(-4)=> 0/9 I think this one would be undefined.
Check to make sure, though!
