Answer:


\textsf{B.} \quad y=3x+2

Explanation:

If two lines are perpendicular to each other, their slopes are negative reciprocals.

The negative reciprocal of a number is -1 divided by the number.

Given equation:


y=-(1)/(3)x+4

The slope of the given equation is -¹/₃

Therefore, the slope of the perpendicular line is:


\implies -1 / -(1)/(3)=-1 * -3=3

Therefore, the equation of the line that is perpendicular to the given equation is:


  • \textsf{B.} \quad y=3x+2

Answer:

  • B) y = 3x + 2

-----------------------------------

Perpendicular lines have opposite-reciprocal slopes.

Given line has a slope of - 1/3, so the perpendicular slope is 3.

The matching choice is B.
