A proportional relationship is also known as a direct variation
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form 
or 
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
In a proportional relationship
If the variable x increases -------> the variable y increases
If the variable x decreases -------> the variable y decreases
Answer:
solution = (1.-2)
Step-by-step explanation:
put x= 1 and y = -2 in this system : y=-4x+2 and y + 2x = 0
you have : - 2 = - 4(1)+2 and -2 +2(1)=0
-2=-2 and 0=0 .....right
Answer:
Step-by-step explanation:
-3x + 9y = -24
3x + 3y = 24
12y = 0
y = 0
-3x + 9(0) = -24
-3x = -24
x = 8
(8,0)
9/10 of 50....." of " means multiply
9/10 * 50 = 450/10 = 45
