K=-13/5

Step-by-step explanation:

Ok so this equation is exactly like a point-slope formula

Y=Mx+b

Think of that k as m

You have b=4 and b is the y-intercept! So that means the coordinates are (0,4)

Now you use slope formula to figure out the slope:

Using (0,4) and (5,-9)

-9-4/5-0 = -13/5

K=-13/5

the answer is a

step-by-step explanation:

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
