Answer:

a ∥ b

Step-by-step explanation:

The symbol "∥" means parallel lines.

Taking a look at the figure above, we have 2 parallel lines, labelled a and b.

A and B are two points on line "a", forming segment AB. However, segment AB is part of line "a".

Same applies to line "b", which has 2 points forming segment CD.

Therefore, the correct label if the parallel lines is a ∥ b

What is the slope of the line passing through the points (0, −5) and (4, 2)?

liraira [26]

$(0,-5) \\
x_1=0 \\ y_1=-5 \\ \\
(4,2) \\
x_2=4 \\ y_2=2 \\ \\
\hbox{the slope } = \frac{y_2-y_1}{x_2-x_1}=\frac{2-(-5)}{4-0}=\frac{2+5}{4}=\frac{7}{4}$

The slope is 7/4.

B-4/6=b/2 solve for b

DIA [1.3K]

First you cross multiply.

2*(b-4)=6b

Then distribute the 2.

2b-8=6b

Minus 2b from each side.

-8=4b

Divide each side by 4.

-2=b

So -2 is your answer.
