Question 185906
Solve the following system of equations by graphing. 4x=4-5y and 4x+5y=10 
a) (4,-2)
b) the equations are dependent
c) the systems is inconsisent
:
-5y=4x-4--->y=(-4/5)x+4/5
5y=-4x+10--->y=(-4/5)x+2
:
these equations have equal slopes of -4/5.....meaning they are parallel and that they have NO solution......so they are inconsistent
:
{{{graph(300,300,-10,10,-10,10,(-4/5)x+4/5,(-4/5)x+2)}}}
