Question

How do you solve the system `2x+4y=8` and `x+y=1` by graphing?

Answer 1

please see below

Explanation:

To solve any set of linear equations graphical method isn't much used because it is time consuming but have a look at it.
`x+y=1` put any 2 distinct values of x to get 2 distinct values of y .
like the set of values could be
`x=1 y=0`
`x=0 y=1`
do the same for other equation . plot these values on graph .since these are linear equations the graph would show a straight line .
the point at which the lines intersect is common solution .
I designed a graph for same at desmos have a look .
