Question

When two straight lines are parallel their slopes are equal.

• A. True
• B. False

Answer 1

The correct option is A

True

Two straight lines are said to be parallel if their slopes are equal.
Slope's defined as
$m=$ $tan\theta =\frac{y}{x}$

If the given lines are parallel, the ratio of their y-intercept to the x-intercept must be equal.
So, any lines parallel to y=mx+c is of the type y=mx+d. Where d is a parameter.
