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.
If you mean a straight line, then 180 degrees.
2
A straight line through the origin, and with a positive gradient (sloping from bottom left to top right).
The one which shows a straight line with a positive gradient of 3 and crossing the y axis at 2.
The gradient of a straight line cannot be defined- it's infinity.
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.
gradient
The gradient of the straight line
Gradient
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.
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.
120?
Yes beccause: (y1-y2)/(x1-x2) = gradient
3/1
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.
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)
