(a) Slope is rise over run, or change in y over change in x.
1 -> 3 ( 
)
2 -> 3 ( 
)
3 -> -1/3 ( 
)
(b) If a line is parallel, the slopes will be the same. If they are perpendicular, the slopes will be are negative reciprocals of one another. If they are neither, then their slopes don't match up in any way.
1 & 2 -> Parallel
1 & 3 -> Perpendicular
2 & 3 -> Perpendicular
Note - Since 1 & 2 are parallel, then both 1 and 2 will be perpendicular to 3!

Answer:
Area 1 is the best option
Step-by-step explanation:
Given Data:
Area 1 = 0.75 dam square
Price = €11,620
Area 2 = 0.009 ha
at €193,500
Area 3 = 0.84a
at €68,900
Where ha ( hectare )
a ( area )
Solution
First we convert all areas to square meter ( m² )
Area 1 = 100 * 0.75 dam square
= 75m²
Cost of area 1/ square meter
= €11,620 / 75m²
= €154.93 / square meter
Area 2 = 0.009 ha * 10,000
= 90m²
Cost of area 2 / square meter
= €193,500 / 90m²
= €2,150 / square meter
Area 3 = 0.84a * 100
= 84m²
= Cost of area 3 / square meter
= €68,900 / 84m²
= €820.23 / square meter
Answer:
i gave you the slope and if its a function
Step-by-step explanation:
it a function
Slope (m) = ΔYΔX= 0
θ = arctan( ΔY )ΔX= 0°
ΔX = 10 – -2 = 12
ΔY = 3 – 3 = 0
Distance (d) = √ΔX2 + ΔY2 = √144 = 12
Equation of the line:
y = 0x + 3
When x=0, y = 3
The constant of proportionality is 1/3
and three more values are
x 1 2 3 4 5
y 3 6 9 12 15
<h3>Variation</h3>
From the question, we are to determine the constant of proportionality
The given equation is
k = x ÷ y
From the given information,
When x = 1, y = 3
∴ k = 1 ÷ 3
k = 1/3
Thus, the constant of proportionality is 1/3
Now, we will determine the values of y for the values x = 3, x = 4, and x = 5
Since
k = x ÷ y
Then,
y = x ÷ k
When x = 3
y = 3 ÷ 1/3
y = 3 × 3
y = 9
When x = 4
y = 4 ÷ 1/3
y = 4 × 3
y = 12
When x = 5
y = 5 ÷ 1/3
y = 5 × 3
y = 15
Hence, the constant of proportionality is 1/3
and three more values are
x 1 2 3 4 5
y 3 6 9 12 15
