This is a linear equation y = mx, where:
m= slope or reading rate:
x = the number of minutes
y = the number of pages read.
So the equation becomes: y = 4.5.x
How many minutes it will take to read 90 pages (y):
90 = 4.5.x or x = 90/4.5 and x = 20 minutes
So the ordered pair will be (20,90)

Answer:
9B^2-12B+4
Step-by-step explanation:
use (a-b)^2 = a^2-2ab+b^2
(3B)^2 - 2x3B x 2 +2^2
raise a product to a power
9B^2-12B+4
