Answer:

  • slope: 0
  • equation: y = -2

Step-by-step explanation:

a) The y-coordinates of points A and B are both -2, so there is no change in the y-value between those points. The x-coordinates differ by 4, so the slope is ...

... slope = (change in y)/(change in x) = 0/4 = 0

b) The y-value is constant at -2 for any value of x, so the equation of the line is ...

... y = -2

1/4x + 5 = 30

-5               -5

1/4x = 25

multiply both sides by 4

x = 100
