2x+y=1 and
2x + 4y = 12
Graph the system of equations

  see below for a graph

Step-by-step explanation:

A graphing calculator makes this short work.

You can find the x- and y-intercepts by setting the opposite variable to zero.

First equation x-intercept is the solution to 2x +0 = 1: x = 1/2. The y-intercept of that equation is the solution to 2·0 +y = 1: y = 1. The graph is the line through these points.

Second equation x-intercept is the solution to 2x +4·0 = 12: x = 6. The y-intercept is the solution to 2·0 +4y = 12: y = 3. The graph is the line through these points.

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

im pretty sure it would be 5 am, hope that , and give brainliest and guys if this is right then press the button and give 5 stars
