find the constant m and b in the linear function f (x) = mx+b so that f (6) = 9 and the straight line represents by f has slope - 4

The constant m=-4, and b=33

Step-by-step explanation:

F (x) = MX+b

If f (6) = 9 then x=6, m = - 4

9 = - 4 (6) + b

9 = - 24 + b

b = 9 + 24

b = 33

Therefore the constant m, which is the slope is - 4 and b which is the intercept is 33
