If it takes you seven minutes to read a page in a book, how many words can you read in one minute? what neccessary piece of information is missing that prevents you from solving the problem

The number of words per page.

Step-by-step explanation:

We're given the time per page. The book could have 10 words or it could have 1,000 words. We wouldn't know until given that information.

I think maybe either how many pages are there or how many words are on each page.

Step-by-step explanation:

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
