How do you work out the gradient of a perpendicular line?
basically the reciprocal of the original lines gradient is going to be the gradient for the perpendicular line (remember the signs should switch). For example if i had a line with the gradient of 3, then the gradient of the perpendicular line will be -1over3. But if the line had the gradient of -3, then the line perpendicular to that line will have the gradient 1over3.
What is a straight angles degrees?
If you mean a straight line, then 180 degrees.
What does y equals -2x-4 equal?
2
Which are the characteristics of proportional relationship graph?
A straight line through the origin, and with a positive gradient (sloping from bottom left to top right).
Which graph represents the equation y equals 3x plus 2?
The one which shows a straight line with a positive gradient of 3 and crossing the y axis at 2.
What is the gradient of a vertical line?
The gradient of a straight line cannot be defined- it's infinity.
What is approximate gradient?
The gradient of a line is the same as the slope of a line. It will tell someone measuring the line how straight the line is.
What does the slope measure?
The gradient of the straight line
What is the slope of a straight line called?
gradient
What is the steepness of a straight line called?
Gradient
What is the gradient of (13) (43)?
If you mean points of (1, 3) and (4, 3) then the gradient is 0 and it is a horizontal straight line parallel to the x axis on the Cartesian plane.
What is gradient of a line?
The slope. The gradient of a straight line is the number of co-ordinates on the y axis to one co-ordinate on the x axis.
If a straight line graph has a gradient of zero it must be horizontal?
120?
Can any 2 points on a straight line be used to find the gradient?
Yes beccause: (y1-y2)/(x1-x2) = gradient
What is the gradient of the straight line y equals 3x plus 1?
3/1
What feature of a distance per time graph represents speed?
The gradient (slope) of the tangent to the graph at the given time - provided that it exists. If the graph is a straight line at that point, it is the gradient of that line.
The slope-intercept equation of a line is y equals mx plus b where m is the slope of the line?
y = mx + c is the equation of a straight oblique line where m = gradient The gradient is a measue of the steepness of a line (or a measure of the slope of the line)
