kaheart [24]

Answer:

positive slope

(0,3)

slope = 2

Step-by-step explanation:

  • Slope of the given line is positive
  • If the line is sloping upward from left to right, so the slope is positive (+).

or if the angle made by the line to the x axis is < 90 it's slope is positive.

  • y-intercept of the line is (0,3)
  • The y intercept is the point where the line crosses the y axis. At this point x = 0.
  • slope of the line is 2
  • slope = (y2 - y1) / (x2 - x1)

    lines passing through points (1,5) (0,3)

    slope = (3 - 5) / (0 - 1)

              = -2 / -1 = 2
