Question

If f(x)=mx+c,f(4)=11 and f(5)=13 then find the value of m and c​

Answer 1

f(5)=13

5m+c=13

f(4)=11

4m+ c=11

subtracting these two eqn

m=2

putting the value of m in any of the above eqn

5m+c=13

5×2+c=13

10+c=13

c=3

Answer 2

Answer:

f(5)=13

5m+c=13

f(4)=11

4m+ c=11

subtracting these two eqn

m=2

putting the value of m in any of the above eqn

5m+c=13

5×2+c=13

10+c=13

c=3
