Question

State whether the lines are parallel, perpendicular, coinciding, or neither y=0.3x+40 and y=-3 1/3x+15

Answer 1

Answer:

Perpendicular

Step-by-step explanation:

The slope of the first equation is 0.3 = 3/10

You need the opposite sign of the reciprocal for perpendicular

10/3 is reciprocal, 3 1/3 is equivalent, - 3 1/3 is perpendicular
