What is the meausure of angle JKL ?

Given the points a(-2, 1) and b(8, 6), find the coordinates of the point c on directed line segment ab, that partitions ab in the ration 2: 3.

One line passes through (-7,-4) and (5,4) . another line passes through the point (-4,6) and (6,-9)

Write the equation for the parabola that has x− intercepts (−2,0) and (4,0) and y− intercept (0,4).
