Answer:
a) Graph are attached ,Red line shows the function y=3x-2 while blue line represents the function y=-5
b)(x,y)=(-1,-5)
Step-by-step explanation:
b)To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.
c)Given that
y=-5
and y=3x-2
compare the right hand side of the above two equation and solve for x
3x-2=-5
or 3x=-3
or x=-1
so the solution to the given system of linear equations is =(-1,-5)
