Sagot :

Answer:

Step-by-step explanation:

  • The first question's slope is 0 because it is a straight horizontal line
  • The second question is undefined because it is a straight vertical line
  • The third question's slope isn't able to be found with a blank line, but the line is positive because the more it travels right, it also goes up. So the slope of the third is positive
  • The fourth is similar to the third as its slope cannot be calculated with a blank line, but the more it moves right, the more it moves down, meaning the slope is negative.
