mber of pages in an album. Which statement describes another point on the graph of this function?

Answer:
50-page photo album holds 400 photograph
Step-by-step explanation:
(3,24)(7,56)
slope = (56 - 24) / (7 - 3) = 32/4 = 8
y = mx + b
slope(m) = 8
(3,24)...x = 3 and y = 24
now we sub
24 = 8(3) + b
24 = 24 + b
24 - 24 = b
0 = b
so ur equation is : y = 8x + 0...or just y = 8x
to find ur answer, take ur answer choices and sub them into y = 8x and whichever one is true is ur answer.
