Passes through
Explanation:
Basically, this is a straight line in the form
Our gradient m is 4 which is positive, so our straight line slopes to the right
You need to solve the equation to see where your line crosses the x and y axis.
- To find y is easy
Let#x=0#
so#y=4(0)-1#
Giving us#y=-1#
So now we know our graph passes through#y=-1# - For x we use a similar process
Let#y=0#
So we get#4x-1=0#
Hence,#x=1/4#
So now we know our graph passes through
