Answer:
(4,-6)
Step-by-step explanation:
1) First, let's find the slope of the line between the two points. Use the slope formula
, substitute the x and y values of (-2,9) and (2,-1) into it, then solve:
![m = \frac{(-1)-(9)}{(2)-(-2)}\\m = \frac{-1-9}{2+2} \\m =\frac{-10}{4} \\m = -\frac{5}{2}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B%28-1%29-%289%29%7D%7B%282%29-%28-2%29%7D%5C%5Cm%20%3D%20%5Cfrac%7B-1-9%7D%7B2%2B2%7D%20%5C%5Cm%20%3D%5Cfrac%7B-10%7D%7B4%7D%20%5C%5Cm%20%3D%20-%5Cfrac%7B5%7D%7B2%7D)
So, the slope of the line is
.
2) Now, using that slope, let's find another point on the line. You can do this by drawing the two points on a graph (picture below). Now, remember that the slope is
. So, starting from any of the two points (I chose (2,-1), as seen below) count 5 units down, then 2 units to the right. This gives an answer, (4,-6).

Answer:
a. isosceles
Step-by-step explanation:
Segments EF and FA of the hexagon are the same length, so the triangle is an <em>isosceles</em> triangle.

Answer:
Step-by-step explanation:
The line with the y-intercept of 2 is solid, so the corresponding inequality will be of the form ...
y ≤ mx +2
The line with the y-intercept of 6 is dashed, so the corresponding inequality will be of the form ...
y < mx +6
The answer choice showing inequalities with these forms is ...
Answer:
Esther didn't divide the area of the faces by 2.
The correct surface area is 72 cm^2
Step-by-step explanation:
Esther didn't divide the area of the faces by 2.
The correct surface area is:
(4 * 4) + 4((4 * 7)/2)
16 + 4(28/2)
16 + 4(14)
16 + 56 = 72 cm^2
