Do the points A(1,3) B(4,2) C(-2,4) lie on the same line? Explain your answer. Show all work.
Jet001 [13]

We can see that

Slope\ of\ AB=Slope\ of\ BC=Slope\ of\ AC

The given points are on same line.

Further explanation:

There are two methods to find if the given points are on same line

  • The slope method: If the points are on same line the slopes of two pairs of points will be same
  • Area of triangle method

Given points are:

A(1,3) B(4,2) C(-2,4)

We will find the slope of AB, BC, and AC

So,

m=\frac{y_2-y_1}{x_2-x_1}

Slope\ of\ AB=\frac{2-3}{4-1} \\=-\frac{1}{3}

Slope\ of\ BC=\frac{4-2}{-2-4}\\ =\frac{2}{-6}\\=-\frac{1}{3}

Slope\ of\ AC= \frac{4-3}{-2-1} \\=-\frac{1}{3}

We can see that

Slope\ of\ AB=Slope\ of\ BC=Slope\ of\ AC

The given points are on same line.

Two families went to Rollercoaster World.
Alona [7]

Answer:

Children ticket cost $30 and adult ticket costs $40.

Step-by-step explanation:

Given that:

x = price of a child ticket

y = price of an adult ticket

According to given statement;

3x+2y=170     Eqn 1

4x+6y=360    Eqn 2

Multiplying Eqn 1 by 3

3(3x+2y=170)

9x+6y=510      Eqn 3

Subtracting Eqn 2 from Eqn 3

(9x+6y)-(4x+6y)=510-360

9x+6y-4x-6y=150

5x=150

Dividing both sides by 5

\frac{5x}{5}=\frac{150}{5}\\x=30

Putting x=30 in Eqn 1

3(30)+2y=170

90+2y=170

2y = 170-90

2y = 80

Dividing both sides by 2

\frac{2y}{2}=\frac{80}{2}\\y=40

Hence,

Children ticket cost $30 and adult ticket costs $40.

Figure 1 and figure 2 are two congruent parallelograms drawn on a coordinate grid as shown below:
LenKa [72]

Answer:

  (a)  Reflection across the y-axis, followed by translation 10 units down

Step-by-step explanation:

Figure 2 is not a reflection across the origin of Figure 1, so neither of the double reflections will map one to the other.

Reflection across the y-axis will put the bottom point at (5, 3). The bottom point on Figure 2 is at (5, -7), so has been translated down by 3-(-7) = 10 units.

Figure 1 is mapped to Figure 2 by reflection over the y-axis and translation down 10 units.
