When given the points (x1,y1) and (x2,y2)
slope=(y2-y1)/(x2-x1)
we have
(3,0) and (3,-2)
(x,y)
x1=3
y1=0
x2=3
y2=-2
slope=(-2-0)/(3-3)=-2/0=undefined since you caon't divide by zero
answer is D
Line 1--------- >(0,2) (1,-1)
y=mx+b m=(-1-2)/(1-0)=-3
2=(-3)*(0)+b----- > b=2
y1=-3x+2Line 2--------- >(0,-1) (2,2)
y=mx+b m=(2+1)/(2-0)=3/2
-1=(3/2)*(0)+b----- > b=-1
y2=(3/2)x-1
<span>using a graphic tool
see attached figure</span>
the best estimate solution for the system is <span>
(1, 1)
because </span>is the only one within the range of the x axis (-5,5) and the y axis (-5,5)
