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
Letx=0
soy=4(0)-1
Giving usy=-1
So now we know our graph passes throughy=-1 - For x we use a similar process
Lety=0
So we get4x-1=0
Hence,x=1/4
So now we know our graph passes through
