Answer:
A
Step-by-step explanation:
The constant of proportionality is the ratio between the two proportional variables in a directly proportional relationship. In this case, the variables are 
and 
.
To find the constant of proportionality, all we have to do is divide any value of by its corresponding value of . Let's take the values in the first row of the table. We know that 
and 
, so the constant of proportionality is 
. Hope this helps!
Trees are important to one's health as they produce oxygen and ate also important to reduce the role of climate change.
<h3>What is health?</h3>

Answer:
6 × 9 = 54
42 ÷ 7 = 6
56 ÷ 7 = 8
Step-by-step explanation:
Given:
6 × 9 = 54
8 × 4 = 34
42 ÷ 7 = 6
64 ÷ 9 = 7
56 ÷ 7 = 8
Now it need to verify,
6 × 9 = 54 this is correct
42 ÷ 7 = 6 This is also correct
56 ÷ 7 = 8 This is correct
Answer:
Not perpendicular
Step-by-step explanation:
Convert it to y-intercept form first:
5x - 4y = -1
-4y = -5x - 1
y = 5/4x + 1/4
4x - y = -9
-y = -4x - 9
y = 4x + 9
y = 5/4x + 1/4
y = 4x + 9
From the slopes, they are not considered perpendicular because one of the line slope is not a <em>negative reciprocal</em> of the other line slope.
