How would I solve 4-3y=31

miskamm [114]

4 - 3y = 31

Subtract 4 from both sides.

-3y = 31 - 4

Simplify.

-3y = 27

Divide both sides by -3.

y = 27/-3

Simplify.

y = -9

Is AB parallel to CD ? Explain.

kolbaska11 [484]

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.
