A keyboarding instructor at a community college collected data comparing a student's age and their typing speed. The equation for the line of best fit is given at y = -1.4x + 117.8, where x is the "age in years" and y is the "typing speed."
If you are 25 years of age. what is your typing speed?
A-153 words per minute
B-83 words per minute
C-63 words per minute
D-102 words per minute
Going off the y=mx+b equation, you would multiply -1.4 by 25 then add 117.8 to that result. The total of your equation would result in 82.8 words per minute.
