Question

The slope of a line is 2/3 . What is the slope of a line that is perpendicular to this line?

Answer 1

Answer:

-3/2

Step-by-step explanation:

With perpendicular lines, the slope switches to its reciprocal and and positive/negative sign switches, i.e, the 2/3 will switch to 3/2 and since the original is positive, the new slope will be negative

Answer 2

Answer:

Slope is -3/2

Step-by-step explanation:

The slope of line that is perpendicular to the line should have a slope that is a negative reciprocal of this slope and multiplying both slopes give us -1

=> The slope of this line is 2/3

=> The slope of line perpendicular to it would be -3/2

Multiplying the two slopes:

=> (2/3)*(-3/2)

=> -1
