New cards
how do you work out the gradient of a line (m)
5
New cards
Give an alternative version of the equation for a line
ax + by + c = 0
6
New cards
What is the intercept method for plotting a graph
To find the y intercept, substitute x=0 into the y=mx + c equation (then you have the y coordinate, with the x coordinate = 0)
To find the x intercept, substitute y=0 into the y=mx + c equation (then you have the x coordinate, with the y coordinate = 0)
