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)

The solution to the absolute value equation 2|x + 8| - 4 = 16 is x = 2 or x = -18

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.

Given the equation:

2|x + 8| - 4 = 16

2|x + 8| = 20

|x + 8| = 10

x + 8 = 10 or -(x + 8) = 10

x = 2 or x = -18

The solution to the absolute value equation 2|x + 8| - 4 = 16 is x = 2 or x = -18
