yes there is a a correlation
f(x) = 4x + 60
slope = 4
y-intercept = 60
Answer:
One solution
Step-by-step explanation:
we have
---> equation A
---> equation B
Solve the system by graphing
Remember that the solution of the system is the intersection point both graphs
using a graphing tool
there's only one point of intersection
so
The solution is the point (0,4)
see the attached figure
therefore
The system of equations has only one solution
R+5=3r+7
-5 -5
r=3r+2
-3r -3r
-2r=2
÷-2 ÷-2
r=-1
