My dad is good at science (Y)
You're thinking of 'inverse' proportion. Here's how it works. Let's say 'y' is proportional to 'x', meaning that a change in 'x' causes a change in 'y'. We also need a constant number, call it 'K'. If 'y' is directlyproportional to 'x', then they both change in the same direction. If 'x' doubles, then 'y' doubles. If 'x' gets 2.93 times bigger, then 'y' also gets 2.93 times bigger etc. You'd express the relationship as: y=Kx. If 'y' is inverselyproportional to 'x', then they change in opposite directions, as you described in your question. If 'x' doubles, then 'y' decreases to 1/2 of what it was originally. If 'x' gets 10 times as big, then 'y' becomes 1/10 as big. This relationship is written: y = K/x.
If quantity A is directly proportional to another quantity B, it means that if B is doubled so is A. When B is tripled so is A. It also works in the other direction; if A is tripled so is B. It works for any factor. In mathematical terms one may write: A = C * B Where C is some numerical constant.

(i) The compound pendulum tends to drag some air with it and this increases the effective mass and hence the moment of inertia of the moving system. (ii) The amplitude of oscillationis finite which needs some correction. (Collected from Practical Physics B y Dr. Giasuddin Ahmad)

Say there are two goods..x and y, which can be substituted with each other..now if the price of good x increases..the consumer will buy less of good x and more of goods y. Since goods x and y are substitute goods..so change in price of goods x will change the demand of good y..so price effect of substitute goods is positive.
When x is nearly zero,y increases in value.
as the y-intercept increases, the graph of the line shifts up. as the y-intercept decreases, the graph of the line shifts down.
The value of x is directly proportional to to the value of y.hence when the value of x increases the value of y decrteses and vice verse
If the slope is negative, y decreases as x increases. The slope goes from top-left of the graph (Quadrant II) to the lower-right of the graph (Quadrant IV).
y=x+2, as x increases, y increases

substitute 0 for y and solve for x. then substitute x for 0 and solve for why and you have the x and y coordinates
Substitute zero for x to find the y-intercept, and substitute zero for y to find the x-intercept.
x-intercept: 1. substitute 0 for y 2. solve for x y-intercept: 1. substitute 0 for x 2. solve for y
To put in something that represents something else.Ex: x=2 y=9Ex: x + y* You would substitute x with 2 and y with 9.
