ANTONII [103]

We are given

First equation:

y=x-1

we can use formula

y=mx+b

slope is m=1

y-intercept is b=-1

y=-2x+5

we can use formula

y=mx+b

slope is m=-2

y-intercept is b=5

Graph:

We can see that

both curves intersect at (2,1)

What is y = 6/3x - 2 in standard form?
umka2103 [35]
Y = 6/3x - 2
Just move x to the other side, 
y - 6/3x = -2
Multiply by -1, 
6/3x - y = 2

In short, Your Answer would be 6/3x - y = 2 or 2x - y = 2

Hope this helps!
