Question

Graph the system of equation below on a piece of paper what is the solution y=x-1 and y=-2x+5

Answer 1

We are given

First equation:

$y=x-1$

we can use formula

$y=mx+b$

slope is m=1

y-intercept is b=-1

Second equation:

$y=-2x+5$

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)

so, solution is x=2 and y=1.................Answer
