Consider the line y=-5/4x +5. Find the equation of the line that is perpendicular to this line and passes through the point (8,5). Find the equation of the line that is parallel to this line and passes through the pint (8,5).

100 points, hi, i’m not sure how to get the equation from the graph and table.

Which system of linear inequalities is represented by the graph?

An automobile assembly line operation has a scheduled mean completion time, μ, of 12 minutes. the standard deviation of completion times is 1.6 minutes. it is claimed that, under new management, the mean completion time has decreased. to test this claim, a random sample of 33 completion times under new management was taken. the sample had a mean of 11.2 minutes. assume that the population is normally distributed. can we support, at the 0.05 level of significance, the claim that the mean completion time has decreased under new management? assume that the standard deviation of completion times has not changed.
