Answer:
A
Step-by-step explanation:
6 is about halfway to 16
21 is about halfway to 56
they meet up, which makes the line the most accurate
Yw :D
The 5 in the ten millions place is 100,000 times greater than the 5 in the hundreds place
Answer:
Yes, y =
x represents a proportional relationship and the constant of proportionality is 
Step-by-step explanation:
<em>The Proportional is a relationship between two quantity one of them equals the product of the other and a constant, where this constant called the constant of proportionality </em>
- If x and y are proportion, then y = k x, where k is the constant of proportionality
- The proportional relationship represented graphically by a line passing through the origin point (0, 0)
Let us solve the question
∵ y =
x
→ It the same as the form of the proportional equation above
∵
is a constant
∴ y is the product of x and constant
∴ y =
x represents a proportional relationship
Substitute x by 0 to find y and show it represented by a line passing through the origin
∵ x = 0
∴ y =
(0) = 0
→ That means point (0, 0) lies on the line which represents the equation
∴ The line which represents this relation is passing through the origin
∴ y =
x represents a proportional relationship
∵ y = kx, k is the constant of proportionality
∵ y =
x
∴ k =
∴ The constant of proportionality is 
Answer:
54. slope: -1/5 y-intercept: -6
55. slope: -3x y-intercept: 12
Step-by-step explanation:
Step-by-step explanation:
Let its complementary angle be x.
So
81+x=90
so, x = 9.
so
complementary angle of 81° is 9°.
