Let's take two points so that we can get the equation of the line which goes through those points. P1 (-9, -2), P2 (3, -17):
So, y is the line which goes through the first and last points of the chart.
To proof that the rest of points go through the line as well, we will evalute each point
Since the evaluation of these points don't correspond to the values of the chart we can assure that the relationship is not linear
If the line is perpendicular, that means the slope has to be opposite, so it will have a slope of -1/2
Fill in the point that it has to pass through on y and x
1=-1/2(0) + b
1=0+b
1=b
Then go back to the standard form y=mx + b and fill in the slope and y intercept
Y= -1/2x + 1
Answer:
<em>12.99</em>
Step-by-step explanation:
<em>a²+b²=c²</em>
<em>a²+b²=c²√91²+√78²=c²</em>
<em>a²+b²=c²√91²+√78²=c²√8281+√6084=c²</em>
<em>a²+b²=c²√91²+√78²=c²√8281+√6084=c²91+78=c²</em>
<em>a²+b²=c²√91²+√78²=c²√8281+√6084=c²91+78=c²169=c²</em>
<em>a²+b²=c²√91²+√78²=c²√8281+√6084=c²91+78=c²169=c²c=√169</em>
<em>a²+b²=c²√91²+√78²=c²√8281+√6084=c²91+78=c²169=c²c=√169 =13</em>

i do not know number 2 sorry
3. (A)
hope it helps have a great day :D
<span><span>1.
</span>Couches = $4 000
Reclining Chairs = $ 2 040
=> Loveseats = $2 800
So, the luxury store went on sale that makes each prices divided 4
=> Couches = 4 000 / 4 = 1 000 dollars
=> 2 couches = 2 000 dollars
=> reclining chairs = 2 040 / 4 =510 dollars
=> 1 reclining chair = 510 dollars
=> Loveseats = 2 800 / 4 = 700 dollars
=> 3 loveseats = 2 100 dollars</span>
