Lines b and c
they both go up 2 and over 1 (rise over run is slope)
Answer:
-14.2
Step-by-step explanation:
f(x)=-3x+5 Write original equation
f(6.4)=-3(6.4)+5 Substitute 6.4 in for x.
=-14.2 Solve
Step-by-step explanation:
b) infinity many solution
If the equation has 0 = 2 then it has no solution
Answer is: infinitely many solutions .
