Try this solution (the way shown is not the shortest one):
The task on the left part:
1. note, the point P and R have coordinates (-4;-4) and (-3;-2).
2. using the coordinates of points P and R it is possible to make up the equation of the required line:
The task of the right part:
1. note, the common view of the equation of the line is y=kx+b, where b - an intersection point of the Y-axis and the given line; k=QR/PQ.
2. according the picture b= -5, k=4/1=5, so <u>y= -4x-5</u>
7/4 - 5/3
(7/4)*(3/3) - (5/3)*(4/4)
(7*3)/(4*3) - (5*4)/(4*3)
21/12 - 20/12
= (21 - 20)/12 = 1/12
