This question may be a bit vague but considering i cant draw the graph i hope someone can still help
I need to find the gradient and y-intercept of a line given, than i need to write the equation of the line.
Now am i correct in saying the y-intercept is where the line crosses on the y point?
If so than it crosses at -1
so how do i than find the gradient if that is all im given?
Yes, you are correct about the y-intercept. In order to find the gradient of a line you need two points. If you know the y-intercept, then you have the point (0,-1). But you have to have another point to find the gradient. What other information are you given? There must be more. Are you given a graph of the line?
okay so i have worked out that the gradient is .5 or 1/2 - but i worked that out by looking at the graph and counting how many sqaures i went up from the y intercept to the x intercept
so now that i have the gradient at .5 or 1/2 how do i write the equation of the line?
