Keshia is reading a 325 page- book at a rate of 25 pages per day . use a point-slope equation to determine whether she will finish reading the book in 10 days

Nice. 

To make the slope we do y = mx + b

She starts from 0 and her rate is 10 pages per day.

y = 25x

Since we need to find when she does reach 325 pages, replace y with 325 as the number of days will multiply the number of pages per day and show us how many days take to reach 325.

325 = 25x 

Simplify.

13 = x

It will take 13 days for her to reach the end of the book. She won't reach the end.

Complementary angles are two angles whose sum is 90 degrees
