If we assume that this trend is linear: (Round your answer to the nearest year) a) Determine an equation in slope-interceptform that relates year and graduation rate. b) Use your equation from parta) to estimate the year in which the graduation rate will be 77.4%

Answer 1

(9) Given that Sheridan collegels graduation rute was ____68.310. 2008 and 7044 2011 so we consider this as a pont (any) - where se denotes the year. - and y denotes the graduation rate (in 1.) so we get ___A (2006, G6:3) , B (2011, 10:4) The required equation is given by y- y = I2 y (x-31) 312-31 4-68-3 = 70.4-68.3 122-2008) 2011 - 2008 y - 68.3 = °*(R-2008) y - 68.3 = 0.72 – 8078 2008 y = 0.72 +6813 – 140.55 -y 20-72 – 1337.3 foi - using con, which obtain en part (9) put y=77.4 77.4 = 0.726 – 1337.3 _0:7343 77.4 +1337.3 -0.7= 1414.7 - a= 141417 = 14147 = 2021 017 X= 2021 le. In 2021 education que graduation rate 77.44
