We are given
First equation:
[tex] y=x-1 [/tex]
we can use formula
[tex] y=mx+b [/tex]
slope is m=1
y-intercept is b=-1
Second equation:
[tex] y=-2x+5 [/tex]
we can use formula
[tex] y=mx+b [/tex]
slope is m=-2
y-intercept is b=5
Graph:
We can see that
both curves intersect at (2,1)
so, solution is x=2 and y=1.................Answer
