Item 6 Graph △JKL and its image after a reflection in the y-axis. J(5, 3), K(1,−2), L(−3, 4)

Answers

Answer 1

Answer:

J(-5,3) K(-1,-2) L(3,4)

Step-by-step explanation:

Reflections over the y axis make the x its opposite. 5 would change to -5, 1 would change to -1, and -3 would change to 3.

Answer 2

When a shape is reflected, it must be reflected across a line.

See attachment for the graph of the image of JKL

The coordinates are given as:

[tex]\mathbf{J = (5,3)}[/tex]

[tex]\mathbf{K = (1,-2)}[/tex]

[tex]\mathbf{L = (-3,4)}[/tex]

The rule of reflection across the y-axis is:

[tex]\mathbf{(x,y) \to (-x,y)}[/tex]

So, the image of the reflection is:

[tex]\mathbf{J'= (-5,3)}[/tex]

[tex]\mathbf{K'= (-1,-2)}[/tex]

[tex]\mathbf{L'= (3,4)}[/tex]

See attachment for the graph of the image of jKL

A line passes through the point (4, –6) and has a slope of Negative three-fourths. Which is the equation of the line?
y = negative three-fourths x minus 3
y = negative three-fourths x minus 6
y = negative 3 x minus three-fourths
y = negative 6 x minus three-fourths

Answers

Answer:

Option A

Step-by-step explanation:

The equation of line is

Solution:

Given that line passes through the point (4, –6) and has a slope of Negative three-fourths

Given point is (x, y) = (4, -6)

The equation of line passing through point (x, y) and slope "m" is given as:

y = mx + c ----- eqn 1

Where "m" is the slope of line and "c" is the y - intercept

Substitute (x, y) = (4, -6) and in eqn 1

The required equation of line is given as:

Thus the equation of line is found

horizontal length = 26

∅ = 24°

We will have to use tangent to solve for the missing length

Step 2: Solve for h

Substitute: tan24° = h/26Multiply both sides by 26: 26tan24° = hRewrite: h = 26tan24°Evaluate: h = 11.5759

What are the coordinates of the midpoint of AB IF A (6,4) and B (-8,8)

Answers

Answer:

-I haven't done this, but I have copied and pasted from another question and answer from the user syed514:

Graphing is one way to do the problem.But sometimes, graphing it is hard to do.So here’s an algebraic method.

If M(m1, m2) is the midpoint of two points A(x1, y1) and B(x2, y2),then m1 = (x1 + x2)/2 and m2 = (y1 + y2)/2.In other words, the x-coordinate of the midpointis the average of the x-coordinates of the two points,and the y-coordinate of the midpointis the average of the y-coordinates of the two points.

Let B have coordinates (x2, y2) in our problem.Then we have that 6 = (2 + x2)/2 and 8 = (3 + y2)/2.

Solving for the coordinates gives x2 = 10, y2 = 13

Which equation represents a proportional relationship?

A. y = x + 1
B. y = 3x + 3
C. y = 4x
D. y = 8 + x

Answers

Answer: C. y=4x

Step-by-step explanation:

Proportional relationship means that the line will be going through the origin, meaning that if the x coordinate is 0, then y has to also equal to 0. Also another way to determine a proportional relationship is by identifying the slope and y intercept. If the line has a y-intercept then it is not proportional because it will not be going through the origin.

y = 4x Input 0 for x and y.

0 = 4(0)

0 = 0

This makes the statement true because if x is 0 then y is also 0.

the answer is C. y=4x
