Question

Keisha is reading a 390 page book at a rate of 28 pages per day. Use a point slope equation to determine how many pages she will have left to read after reading the book for 10 days

Answer 1

Point slope equation:

(y-y1) =m (x-x1)

x1,y1 are points of the line

m= slope

390 pages book

Rate of 28 pages per day.

x= number of days

y= number of pages

y = 28x

The slope is 28.

(y-y1) = 28 (x-x1)
