Answer:
y=2x+3 is non-proportional. y=5x is proportional.
Step-by-step explanation:
y=2x+3 is not proportional because there is the +3. also, when it is graphed on a graph, the line does not pass through the origin/zero.
y=5x is proportional because it does not have any other values attached to the y value. when it is graphed, the lie goes through the origin/zero.
X-3y=-15
-3y=-x-15
-1(-3y=-x-15)
3y=x+15
3/3y=1/3x+15/3
y=1/3x+5
Here we are supposed to find the distance between the two points
Suppose A=(-8,-9), B=(-4,-10)
Now As per the distance formula we know that the distance between two points is given by the formula

This is not true.


where is
is any integer. So suppose we pick some value of
other than these, say
. Then
