What is the equation of this line? graph of a line on a coordinate plane. the horizontal x axis ranges from negative 10 to 10 in increments of 1. the vertical y axis ranges from negative 10 to 10 in increments of 1. a line passes through the points begin ordered pair negative 9 comma negative 8 end ordered pair and begin ordered pair 2 comma negative 4 end ordered pair. enter your answer in the box, in slope-intercept form

Name each raycalculation tip: in ray "ab", a is the endpoint of the ray.

Suppose that 3% of all athletes are using the endurance-enhancing hormone epo (you should be able to simply compute the percentage of all athletes that are not using epo). for our purposes, a “positive” test result is one that indicates presence of epo in an athlete’s bloodstream. the probability of a positive result, given the presence of epo is .99. the probability of a negative result, when epo is not present, is .90. what is the probability that a randomly selected athlete tests positive for epo? 0.0297

Find the length of the normal and the angle it makes with the positive x-axis. (see pictured below)
