Which of the equations below is the equation of a line perpendicular to y = 1 over 4 x − 6 that passes through the point (−1, 5)? y − 5 = 1 over 4 (x − (−1))
y − (−1) = 1 over 4 (x − 5)
y − (−1) = −4(x − 5)
y − 5 = −4(x − (−1))

The customer price index(cpi), which measures the cost of a typical package of customer goods,was 208.8 in 2011 and 244.1 in 2016.let x=11 corresponding to the year 2011 an estimate to cpi into 2013 and 2014. assume that the data can be modeled by a straight line and the trend to continue idenfinitely.use data points to find such a line and then estimate the requested quantities
