The standard set up would be to move up for positive values and down for negative.
-- Remember which one was positive and which was negative, then forget about the signs.-- Write down the one that was positive-- Subtract from it the one that was negative(Notice that if the negative one was bigger, then the answer will be negative.)
Assuming that a is the leading coefficient of the equation of the parabola, changing it from positive to negative will reflect the parabola along a horizontal line through its minimum - which will then become its maximum.
Step 1: Solve for y so that your equation is in the form of y=mx+b Step 2: your m value is your y- intercept. So put the point (0,m) on the graph Step 3: your b value is your slope of the equation. If your b value is already a fraction then the numerator is your "rise" and the denominator is your "run." If your b value is not a fraction then just make it into one by putting a fraction bar and a 1 underneath it. Now starting from the first point you put, go up or down the amount of your "rise" and mark the point. Positive is up and negative is down. For example if your "rise" is -3 then go down three points from your y intercept. Now from your second point, go left or right depending on your "run" and make a point. Positive is right and negative is left. For example, if my "run" is 5 then I will move 5 right and make a point. Step 4: Connect your first and third point with a straight line and extend the line. Put arrow heads on both ends of your line and that is your equation of a line on a graph.
Start at zero and move the value of the first number right (move left if negative) Then move up the value of the second number (down if negative)
words that are equal to positive are increase, north, east, above,raising, up and etc. words that are equal to negative are decrease, diminished, south, west, down and etc.
In this case, acceleration is positive. Negative acceleration would cause the object to slow down (decelerate.)
The point that moves (if none a new point is made) goes up or down the graph. Up is a positive number. Down is a negative number.
Positive acceleration = speeding up. Negative acceleration = slowing down.
Positive is speeding up and negative is slowing down
negative is up and postive is down
Imagine a rocket ship which can either be pointing up (positive) or down (negative). The rocket ship has forward thrusters (positive) and reverse thrusters (negative).Now if the spaceship is pointing down (negative) AND fires its reverse thrusters (negative) it goes UP (positive). So negative and negative make positive.Other permutations are possible. For example, if the spaceship is facing down and fires its forward thrusters, it goes DOWN. So a negative and a positive make a negative.

positive is 1 and up and negative is -1 and down. Tyler fogarty
the charge of a lightning is positive and negative. The positive is on the top of a lightning cloud and the negative is surrounded on the bottom. As it flashes down it is a negative. However, the ground is a positive charge so as it reaches down, it turns into a positive charge. I hope this will answer you question
Positive acceleration ==> speeding up Negative acceleration ==> slowing down
Its a positive for the baby.
Positive g-force is down. Negative g-force is up.
