Triangle JKL is graphed on the coordinate plane and translated 4 units right and 3 units down. What is the y-coordinate of point K'?
J(-1,3) K(-1, 1) L(-4,1)

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

49/6 is going to equal 8 1/6

perpendicular to x*4 means it's y = -1/4*x+k

so for y = 7 and x = 2

we have 7 = -1/4*2 + k so k = 7.5

so the equation is   y = -1/4x + 7.5
