Solve the linear system -x+2y=3 and 2x+y=4 by graphing

  (x, y) = (1, 2)

Step-by-step explanation:

Given the features of graphing calculators these days, obtaining a solution by graphing is one of my favorite methods. The attached graph shows the solution to be (x, y) = (1, 2).

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
