when do y values have positive direction?

When the line is above the x axis

when do y values have a negative direction

when the line is below the x axis

When is the Y value increasing (magnitude)

when the line moving away from the x axis (angled away from x)

When is the Y value decreasing (magnitude)

getting closer and closer towards the 0 (angled toward x)

When the Y value constant (magnitude)

when the line horizontal (no change is happening)

Slope is positive when

the line is angled up and to the right

Slope is negative when

the line is angled down

The slope is zero when

the line is zero, no change happening

The slope increases when (magnitude)

the line is curves to be more vertical

the slope decreases when (magnitude)

the line curves to less vertical

the slope is constant when (magnitude)

the line is straight

position is positive when (direction)

the object is on the positive side of reference point that we define. X axis: on the right side Y axis: above the ref point

position is negative when (direction)

the object is on the negative side of the reference point, that we have define x: on the left side y: above the reference point.

position is constant when (direction)

the object is at the reference point same for x and y directions

the amount of position increases when (magnitude)

the object moves away from the reference point in that particular direction

the amount of position decreases when (magnitude)

moving towards the reference point in a particular direction

the amount of position stays constant when (magnitude)

the object is not in a particular direction (with respect to the reference point)

Velocity’s direction is positive when

no matter where the object is it’s moving towards the positive direction. X axis: moving to the right Y axis: moving upwards

Velocity’s direction is negative when

No matter where an object is, it is moving towards the negative direction, X axis: moving to the left Y: moving downwards

Velocity’s direction is zero when

No matter where the object is it is not moving in a direction.

the amount of velocity increases when (magnitude)

the object is speeding up

the amount of velocity decreases when (magnitude)

the object is slowing down

the amount of velocity stays constant when (magnitude)

the object is not speeding or slowing down, either object isn’t moving or the object is moving with an unchanging speed.

the direction of acceleration is positive when

no matter where an object is, it is being pushed in a positive direction x axis: pushed to right y axis: pushed upwards

the direction of acceleration is negative when

no matter where an object ism it is being pushed in a negative direction. X axis: pushed to the left Y axis: pushed downwards

the direction of acceleration is 0 when

no matter where an object is it is, there are no pushes overall. Either the pushes cancel out or there are none.

the amount of acceleration increases when (magnitude)

the push on the object gets stronger

the amount of acceleration decreases when (magnitude)

the push on the object gets weaker

the amount of acceleration remains constant when (magnitude)

the push on the object remains the same

when is the y values zero

when the line is on the x axis
