What's That
-3+n=3
n=6
12x3
36
Decrease
Lesser in Value, fewer, smaller
In which quadrant would you find the coordinates (-2,-3)?
Quadrant 3
When a line goes through the origin, does that present a proportional relationship?
Yes because the straight line goes through the origin.
15=x+17
x=-2
-8x4
-32
Difference
The result of a subtraction problem
In which quadrant would you find the coordinates (4,3)
Quadrant 1
If x stands for 2, 3, 4,
Y stands for 8, 12, 16
What is the constant of proportionality?
4 because the constant of proportionality is calculated by y/x
-64=-8y
y=8
-7x(-6)
42
Product
The result of a multiplication problem
In which quadrant would you find the coordinates (3,2)
Quadrant 1
Find the constant of proportionality of the points (4,10) and (2,5)
2.5 because 10/4 and 5/2 both give us 2.5
16=16y
y=1
-21/3
-7
Reciprocal
The multiplicative inverse of an expression.
On which axis is the point (-2, 0) located?
x-axis
If x values are 1, 3, 5
The y values are 4, 7, 8
Does the this represent a proportional relationship?
No because the ratios are not constant.
b/11=8
b=88
