Question

Is AB parallel to CD ? Explain.

Answer 1

Answer:

Its C.

Step-by-step explanation:

Answer 2

Answer: The correct option is A because the lien have same slope.

Explanation:

The formula to find the slope is,

$m=\frac{y_2-y_1}{x_2-x_1}$

From the given figure A(-3,-3) and B(0,1), So the slope of AB is,

$m_1=\frac{1-(-3)}{0-(-3)} =\frac{1+3}{3}= \frac{4}{3}$

From the given figure C(0,-5) and D(3,-1), So the slope of CD is,

$m_2=\frac{-1-(-5)}{3-0} =\frac{-1+5}{3}= \frac{4}{3}$

The slope of parallel lines are same.

Since the slope of AB and CD are same, therefore we can conclude that the lines AB and CD are parallel and option A is correct.
