Select the correct answer from each drop-down menu. the equation from the graphed line in slope-point form using the point 2,-1 ) is
( y + 1 = 4x-8)or (y +1 = 1/4(x-2) and it’s equation in slope-intercept form is (y=x/4-3/2) or (4y=x-6)

There are two major tests of readiness for college: the act and the sat. act scores are reported on a scale from 1 to 36. the distribution of act scores in recent years has been roughly normal with mean µ = 20.9 and standard deviation s = 4.8. sat scores are reported on a scale from 400 to 1600. sat scores have been roughly normal with mean µ = 1026 and standard deviation s = 209. reports on a student's act or sat usually give the percentile as well as the actual score. the percentile is just the cumulative proportion stated as a percent: the percent of all scores that were lower than this one. tanya scores 1260 on the sat. what is her percentile (± 1)?
