P=-30h+74 The variable h represents the number of hours he has spent reading, the variable p represents the number of pages left to read. How many hours of reading will Ethan have to do in order to have 14 pages left to read?

Ethan will have to spend 2 hours reading if 14 pages are left to read

Step-by-step explanation:

Given the equation

P=-30h+74

where p =number of pages left to read and

h= the number of hours he has spent reading

Therefore , if Ethan has 14 pages left to read, then the number of hours Ethan will have to read will be

P=-30h+74

14= -30h + 74

30h= 74-14

30h= 60

h = 60/30

h =2 hours

Ethan will have to spend 2 hours reading if 14 pages are left to read

Step-by-step explanation:

We know that the general intercept form of equation of line is given by :-

, where m is the slope of the line.

The given equation of line :

Dividing both sides by 3 we get

Comparing the equation to the general intercept form of equation of line , we get

The slope of the line (m)=2

Hence, the slope of the line whose equation is is 2.
