Question

The following points are plotted in x, y plane. Find the slope and the y intercept of the line joining each pair of points. a. (0,4) and (3,4)

Answer 1

Answer:

A = (0,4) ; B = (3,4)

Slope m = (y2 - y1)/(x2-x1)

              = (4-4)/(3-0)

              = 0/3

              = 0

Equation of line :-

y = mx + c

4 = (0)(0) + c

c = 4

y intercept = 4
