The solution is (-17,80.5) and (1,8.5)
Step-by-step explanation:
Equation 1 :
Equation 2:
Substitute the value of y from equation 2 in equation 1
Equation 1 :
After substitution :
Substitute the value of x = -17
y = -4x+12.5
y = -4(-17)+12.5
y=80.5
Substitute the value of x = 1
y = -4(1)+12.5
y=8.5
Hence the solution is (-17,80.5) and (1,8.5)
D. The others could be faked.
