Solve by Equation

2 + 3y = 8 equation (1)
4x - y = 2 equation (2)

Equation (1) - (2)

2 - 4x + 3y - y = 8 - 2

-4x + 2y + 2 = 6

-4x + 2y + 2 -6 = 0

-4x + 2y -4 = 0

2y = 4x + 4

y = 2x + 2 equation (3)

In equation (1),

2 + 3(2x + 2) = 8

2 + 6x + 6 = 8

6x = 8 - 6 - 2

6x = 0

x = 0

In equation (2),

4(0) - y = 2

0 - y = 2

-y = 2

y = -2

Answer x = 0 and y = -2

Dilate line f by a scale factor of 2 with the center of dilation at the origin to create line f'. Where are points A' and B' loc

miss Akunina [59]

Answer:

Option (1).

Step-by-step explanation:

Given question is incomplete: find the complete question in the attachment.

From the given figure, coordinates of the points A and B are (0, 2) and (2, 0) respectively.

Slope of line AB = $\frac{(y_{2}-y_{1})}{(x_{2}-x_{1})}$

$m_{1}=\frac{2-0}{0-2}=-1$

When these points are dilated by a scale factor = 2, about the origin

Rule for the dilation → (x, y) → (kx, ky)

Where k = scale factor

Coordinates of the points A' and B' will be (0, 4) and (4, 0)

Slope of the line A'B' = $\frac{(y_{2}-y_{1})}{(x_{2}-x_{1})}$

$m_{2}=\frac{4-0}{0-4}=-1$

Since $m_{1}=m_{2}$ , both the lines AB and A'B' will be parallel.

Therefore, option (1) will be the answer.
