Answer:
Line l (red line): y=4
Line m (black line): y=-2x+4 or y=4-2x
Line n (green line): y=x-1
Line p (blue line): x=-4
Step-by-step explanation:
Line l (red line):
Line l is horizontal. Horizontal lines have y equal to a constant, in this case 4.
y=4
Line m (black line):
Find slope using two points (0,4) and (2,0)
(y2-y1)/(x2-x1)
(4-0)/(0-2)
4/-2
-2
y=mx+c, where m is the slope and c is a number
y=-2x+c
sub in a point (eg (-1,6))
6=-2(-1)+c
6=2+c
c=4
y=-2x+4 or y=4-2x
Line n (green line):
Find slope using two points (3,2) and (2,1)
(y2-y1)/(x2-x1)
(2-1)/(3-2)
1/1
1
y=mx+c, where m is the slope and c is a number
y=1x+c
y=x+c
sub in a point (eg (1,0))
0=1+c
c=-1
y=x-1
Line p (blue line):
X value is constant at -4. x=-4
