we have the system of equations

y=(4/5)x-3 -------> equation A

y=(4/5)x+1 -----> equation B

In this problem

we have two parallel lines with different y-intercept

because the slopes are equal

that means

The system has no solution

Part b

Solving the system by substitution

equate equation A and equation B

(4/5)x-3=(4/5)x+1

simplify

-3=1 -----> is not true

that means

the system has no solution
