Answer:
It's C
The X and Y coordinates are both negative
Step-by-step explanation:
Quadrant 1- negative and positive
Quadrant 2- positive and positive
Quadrant 3- negative and negative
Quadrant 4-positive and negative
Answer:
4
Step-by-step explanation:
gradient=vertical distance /Horizontal distance
G=V/H
G = -4/-1
G =4
X -y = -5
To see that substitute the points.
First, point (-2,3)
-2 - 3 = -5
Now second point (2,7)
2 - 7 = -5
As you have seen, both points belong to the equation x - y = -5
Answer:
The constant of proportionality is 5
<em></em>
Step-by-step explanation:
Given
--- Cost
--- Number of shirts
Required
Determine the constant of proportionality
The relationship between y and x is:

Where:
k = constant of proportionality
Substitute
and 


Divide both sides by 6




<em>The constant of proportionality is 5</em>
