Ur asking for slope intercept form, but ur answer choices are in point slope form....so I am gonna find the answer in point slope form.
y - y1 = m(x - x1) slope(m) = 2/3 (5,-3)....x1 = 5 and y1 = -3 now we sub...but pay very close attention to ur signs y - (-3) = 2/3(x - 5) = y + 3 = 2/3(x - 5) <=== ur answer in point slope form
Let x = the number of students at Taft high school 5x-100 = the number of students at Jefferson high school if x =300 than 5(300)-100=1500-100=1400 students at Jefferson high school
