If a line passes through the points (1,3) and (-2,-9), the equation of the line is y - 3 = 4(x - ___).
It's clear from the given point-slope equation of the line, y - 3 = 4(x - ), that the coordinate point, (1, 3) was used. 

Therefore, it's highlight_green%28matrix%281%2C3%2C+y+-+3%2C+%22=%22%2C+4%28x+-+1%29%29%29
