The graph and table shows the relationship between y, the number of words Jean has typed for her essay and x, the number of minutes she has been typing on the computer. According to the line of best fit, about how many words will Jean have typed when she completes 60 minutes of typing?

We are given the following variables:

y = number of words Jean has typed for her essay

x = the number of minutes she has been typing on the computer

If there is a given equation of this form: y = mx + b, where the slope is m and b is the y-intercept. We can determine the number of words Jean typed for 60 minutes.

x = 60 minutes

solve for y:

Assuming that the equation of the line is y = 20x + 10

then substitute x with 60 minutes and solve for y,

y = 20 (60) + 10

y = 1200 + 10

y = 1300 words
