Hello and Good Morning/Afternoon:
<u>Let's take this problem step-by-step:</u>
<u>First off, let's write the line in point-slope form:</u>
- (x₀, y₀) any random point on the line
- 'm' is the value of the slope
<u>Let's calculate the slope:</u>
- (x₁, y₁): any random point on the line ⇒ (-2, -6)
- (x₂,y₂): any random point on the line that is not (x₁, y₁) ⇒ (2, -3)
<u>Now that we found the slope, let's put it into the point-slope form</u>
⇒ we need (x₀, y₀) ⇒ let's use (2,-3)
<u>The equation, however, could also be put into 'slope-intercept form'</u>
⇒ gotten by isolating the 'y' variable to the left
<u>Answer:</u> or
*<em>Either equations work, put the one that you are the most familiar with</em>

Answer:
<h3>The function formula for the number of pages left to read is given by P(t)=55(10-t).</h3>Step-by-step explanation:
Given that "Naoya read a book at a rate of 55 pages per hour".
After reading book for 4 hours, he had 330 pages remaining to read.
In 4 hours, Naoya must read is given by
( by given)
From the given there were 330 pages remaining to read at the time,
The total number of pages is given by
=220+330
=550
<h3>∴ The total number of pages is 550 </h3>For each hour of reading, Naoya reads 55 pages, so the number of pages he finished reading by the "t"th hour is given by 55t
Let P(t) be the number of pages to read where P is a function of time t (measured in hours)
So the number of pages left to read is given by
P(t)=550-55t
P(t)=55(10-t)
<h3>∴ the function formula for the number of pages left to read is given by P(t)=55(10-t).</h3>
