step 1
<em>Find the value of k</em>
For the point (3,24)
x=3,y=24
k=y/x
k=24/3=8
The equation is equal to
y=8x
step 2
<em>Verify each statement</em>
case A) 50-page photo album holds 400 photographs.
For x=50
substitute in the equation
y=8(50)=400 -----> is correct
case B) 80-page photo album holds 560 photographs.
For x=80
substitute in the equation
y=8(80)=640 -----> is not correct
case C) 100-page photo album holds 8,000 photographs.
For x=100
substitute in the equation
y=8(100)=800 -----> is not correct
case D) 900-page photo album holds 8,400 photographs.
