Answer:
y = -2x + 3
Step-by-step explanation:
Let's just put the three points together.
(-1, 5) (-4, 11) (-7, 17)
First, let's find the slope with y2 - y1/x2 - x1
Plug in using (-1, 5) and (-4, 11)
11 - 5/-4 + 1 = 6/-3 (simplify)
-2 is the slope
Now plug in (-7, 17) in the equation to get b or the y-intercept)
y = mx + b
17 = -2(-7) + b
17 = 14 + b (subtract 14 on both sides)
3 = b
y = -2x + 3

Which of the following translations is needed to carry AEFG onto its image AEFG'?
Answers
Answer:
Option B
Step-by-step explanation:
It's given that ΔE'F'G' is the translated image of ΔEFG.
Let the ΔEFG has been translated 'h' units on x-axis and moved by 'k' units on y-axis.
Let's choose a point E having coordinates (-5, -7)
By the rule of translation, coordinates of the image point E' will be,
E(-5, -7) → E'(-5 + h, -7 + k)
Coordinates of the image point E' → (-9, 4)
Comparing both the coordinates of E',
E'(-5 + h, -7 + k) = E'(-9, 4)
-5 + h = -9
h = -9 + 5
h = -4
-7 + k = 4
k = 4 + 7
k = 11
Therefore, rule for the translation will be,
E(-5, -7) → E'(-5 - 4, -7 + 11)
(x, y) → (x - 4, y + 11)
Option B is the answer.

Answer:
BC ≈ 17.0 (neither Crow nor Toad is correct)
Step-by-step explanation:
The left-side ratio of (2+4)/4 = 3/2 suggests BC is 3/2 times the length DE. If that were the case, BC = (3/2)(11) = 16.5, as Crow says.
The right-side ratio of (5+9)/9 = 14/9 suggests that BC 9 is 14/9 times the length DE. If that were the case, BC = (14/9)(11) = 154/9 = 17 1/9 ≈ 17.1, as Toad says.
The different ratios of the two sides (3/2 vs 14/9) tell you that the triangles are NOT similar, so the length of BC cannot be found by referring to the ratios of the given sides.
Rather, the Law of Cosines must be invoked, first to find angle A (109.471°), then to use that angle to compute the length of BC given the side lengths AB and AC. That computation gives BC ≈ 16.971. (See the second attachment.)

Answer:
x = 11 , y = [tex]\frac{8}{3}[/tex]
Step-by-step explanation:
The opposite sides of a parallelogram are congruent
For the figure to be a parallelogram , then
ON = LM, that is
5x - 7 = 4x + 4 ( subtract 4x from both sides )
x - 7 = 4 ( add 7 to both sides )
x = 11
and
OL = NM , that is
3y - 4 = x - 7 = 11 - 7 = 4 ( add 4 to both sides )
3y = 8 ( divide both sides by 3 )
y = [tex]\frac{8}{3}[/tex]
