Question

solve by graphing (x,y) like that x-6=-3y -4x=-3y-9

Answer 1

since the question asked to solve it by graphing, i think u have to sketch the graph of the 3equations and the answer is the point of interception of all graphs

Answer 2

sorry, there is only 2graphs

Answer 3

okay

Answer 4

thank u

Answer 5

Attached is a plot of interest. It is a partial screen capture from the web site, wolframalpha.com.

Each of the equations were solved for y. The required plot text was formulated and plugged into the solution request box:

plot {1/3(-9 + 4 x),(6-x)/3},{x, 2.5, 3.5}

By inspection is appears that the solution is (3,1).
