Question

Part 1: Explain, in complete sentences, how you would use the graphing method to solve the following system of equations. Part 2: Provide the solution to the system. Part 3: Explain what the solution represents on the graph.
x + 4y = –16
3x + 2y = 12
please help

Answer 1

Part 1:
First rearrange both equations to express y with the subject x.
Thus getting,
y= (-16-x)/4
y= (12-3x)/2

Then graph this 2 equations, with the help of a graphing calculator, or without.
You will then get 2 straight lines.
Find the intersection point of the 2 lines. That will be the solution for the system of equations.

Part 2:

Via the graphing method i got
x=8
y=-6

Part 3: (this is kind of repetitive as i answered this in part 1 already)
The solution represents the point of intersection of the 2 lines on the graph.
