YOU HAVE TO FIND THE SLOPE m
The formula to find the slope is m=(y₂-y₁)/(x₂-x₁)
Since we have the coordinate of each point, then we can calculate the slope m
7) (-6-3)/(2+4) = -9/6 =-3/2 (slope negative so the function falls
8) (-1-1)/(7-7) = -2/0 (tan ---> ∞ ) VERTICAL
9) (-2+2)/(5-3) = 0/2 = 0 slope = 0 ===> Horizontal
For inverse variation, we use the equation y = k/x, again, with k as the constant of proportionality. <span>When one variable increases the other decreases in proportion so that the product is unchanged. Therefore, it would be the last option the correct answer.
y = k / x
2 = k / 4
k = 8</span>
-4(5g+8s=22.87)
5(4g+7s=18.89)
-20g-32s=-91.48
20g+35s=94.45
3s=2.97
s=.99
7(.99)+4g=18.89
6.93+4g=18.99
4g=13.6
g=3.4
It can make the shape bigger or smaller
I think a partial variation
