Answer:
-3
Step-by-step explanation:
Parallel lines have slopes that are the same.
So if one line has a slope that is -3, any line that is parallel will have the same slope
Rewriting input as fractions if necessary:
7/1, 343/1
For the denominators (1, 1) the least common multiple (LCM<span>) is </span>1.
Therefore, the least common denominator (LCD<span>) is </span>1.
<span>Rewriting the original inputs as equivalent fractions with the </span>LCD:
<span>7/1, 343/1</span>
(1) t+w=15 ==> t=15-w
(2) 2*t ==>2*(15-w)=40-2w
(2) 30-2w=40-2w
==> 0w=10
so that there is no solution which means inconsistent.
Answer:
y= -1/2x
Step-by-step explanation:
y-y1/x-x1=y2-y1/x2-x1
y-1/x+2=-1/2
2y-2= -x-2
2y= -x-2+2
2y=-x
y=-1x/2„
