True or False?
On a coordinate grid, the point which is 3 units right and 4 units up from the origin has coordinates (3,4).
True.
On a coordinate grid, the point which is 3 units right and 4 units up from the origin has coordinates (3,4).
Which coordinates would be units left and units down from the point ?
The coordinates units left and units down from the point would be .
State an expression for the coordinates of the midpoint between and .
The midpoint between and is given by the expression .
True or False?
The x-coordinate of the midpoint is equal to the mean of the x-coordinates of the two points.
True.
The x-coordinate of the midpoint is equal to the mean of the x-coordinates of the two points.
The y-coordinate of the midpoint is also equal to the mean of the y-coordinates of the two points.
What does the gradient of a line measure?
The gradient of a line measures the steepness of the line.
True or False?
A line with a gradient of -4 is steeper than a line with a gradient of -5.
False.
A line with a gradient of -5 is steeper than a line with a gradient of -4. The steeper line is the one with the bigger gradient value when you ignore negative signs.
True or False?
The gradient of a line is equal to .
True.
The gradient of a line is equal to .
State the formula for the gradient of the line that passes through and .
The formula for the gradient of the line that passes through and is .
The formula will also give the gradient.
True or False?
A positive gradient means the line goes upwards from bottom left to top right.
True.
A positive gradient means the line goes upwards from bottom left to top right.
True or False?
The gradient of the line which passes through and can be found by calculating .
False.
The gradient of the line which passes through and can not be found by calculating .
The order needs to be consistent. If the second coordinate is used first for the coordinates, then the second coordinate should be used first for the coordinates.
It should be either or .
State the formula for the length of the line segment between and .
The formula for the length of the line segment between and is .
This is just using Pythagoras' theorem on the line segment between the two points.
True or False?
The length of the line segment between and can be found by calculating .
False.
The length of the line segment between and can not be found by calculating . Each bracket should be the difference between the values or the values.
It should be .
