Question

The lines below are parallel. If the slope of the green line is –3, what is the slope of the red line?

Answer 1

The slope of the red line should be -3 as well since they are parallel lines
 

Answer 2

Answer:

Slope = -3

Step-by-step explanation:

We are given that the two lines are parallel to each other. And we know that if two lines are parallel to each other then their slopes are equal. As the slope of green line is -3 , the slope of red line will also be -3.

The slope of any line represents the tangent of the angle which the line makes with the positive direction of x axis. As both the lines are parallel, they have same slope which is -3
