a. The slope between (-3, 0) and (0, -1) is: -1/3.

b. The slope between (1, -4) and (-7, 4) is: -1.

c. The relationship is not linear.

<h3>How to Calculate the Slope?</h3>

We can find the slope of a relationship that is represented by a table of values by using two points from the table, then apply the formula below:

Slope (m) = change in y/change in x = \frac{y_2 - y_1}{x_2 - x_1}.

Part A: Using two points from the table, (-3, 0) and (0, -1)

Slope (m) = change in y / change in x = (-1 - 0) / (0 - (-3))

Slope (m) = -1/3

Part B: Using another two points, say (1, -4) and (-7, 4)

Slope (m) = change in y / change in x = (4 - (-4)) / (-7 - 1)

Slope (m) = 8/-8

m = -1

Part C: The slopes from part A and part B are not the same or constant, this shows that the relationship between the points is not linear.

Is 5/8 more than 2/3
Andre45 [30]
No. 2/3 is bigger than 5/8 because if you convert them to where the denominator is the same, 5/8= 15/24 and 2/3 is equal to 16/24

Nikolay [14]

The length of the ladder nearest hundredth of a foot is 23 feet.

We have given that,

An electrician leans an extension ladder against the outside wall of a house so that it reaches an electric box 20 feet up.

The ladder makes an angle of 77^{\circ}  the ground.

<h3>What is the sin ratio?</h3>

sin(\theta)=\frac{perpendicular \ side}{hypotenous}

Therefore we get,

\implies\frac{22}{H} =sin(77)

\implies H=22/sin(77)

\implies 22.59ft\\\\=23ft

Therefore, The length of the ladder nearest hundredth of a foot is 23 feet.
