+27 Interpret the Slope and Y-intercept.
A student with no previous typing exprience takes a 3-week typing course and after each day takes a test. The speed is recorded in word per minute (wpm). A linear regression equation that models the student's results is found to be y=23.5+2.0x where x= the number of days after the student started the course and y= the student's recorded typing speed.
