Answer:

Slope of Line B = 3/5.

Explanation:

Relating the slopes of perpendicular lines:

  • The slopes of perpendicular lines are negative reciprocals of each other.

We can see this with the equation m2 = -1 / m1, where

  • m2 is the slope of the other line (i.e., Line B in this case),
  • and m1 is the slope of the line we're given (i.e., -5/3 from Line A).

Finding m2, the slope of the other line:

Thus, we can find m2, the slope of Line B by substituting -5/3 for m1 in the perpendicular slope formula above:

m2 = -1 / (-5/3)

m2 = -1 * -3/5

m2 = 3/5

Thus, the slope of Line B is 3/5.
