How do you find the y-intercept of the trend line?
Find the value of the trend line when x = 0
How do you find the gradient of a line?
i think you do Vertical/horizontal
How do you find the average of a line plot?
divide by the gradient
How to calculate the gradient from the non linear graph?
Draw a tangent to the curve at the point where you need the gradient and find the gradient of the line by using gradient = up divided by across
Can any 2 points on a straight line be used to find the gradient?
Yes beccause: (y1-y2)/(x1-x2) = gradient

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.

The line L has an equation 5x+7y = 3. Find the gradient of line L?
-5/7

Yes beccause: (y1-y2)/(x1-x2) = gradient
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.
How does a gradient affect the steepness of the line?
The higher the gradient, the more steeper the line will be.
How do you find a gradient of a line without a graph?
Select two values of x: (x1 and x2) within the domain. Solve the equation of the line to find the corresponding values for y: (y1 and y2). Then the gradient = (y1 - y2) / (x1 - x2)
What is the gradient of a vertical line?
The gradient of a straight line cannot be defined- it's infinity.
Which type of line represents a trend in the data on a graph?
trend line
