Help me on this question please

j = h + 9

Step-by-step explanation:

To go from 3 to 12, add 9 to 3. Add 9 to 4 to get 13. Add 9 to 5 to get 14.

In each case, add 9 to the value of h to get j.

j = h + 9

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
