Extracted text: (d) the slope b (e) the y-intercept a (f) find the correlation r Instruction for entering answer: Enter integers as integers and then any number with decimal result only with only two significant decimals (for example if the answer is 10 enter as 10, if the answer is 2.15 enter as 2.15 -for answers s with more than two decimal places enter it to decimal places- thus if the answer is 2.1538 enter as 2.15, if the answer is 2.1583 as 2.16)
