\left\{\begin{array}{ccc}y=3x-4\\y=-2x+1\end{array}\right\\\\y=3x-4\\for\ x=0\to y=3(0)-4=-4\to(0;-4)\\for\ x=2\to y=3(2)-4=2\to(2;\ 2)\\\\y=-2x+1\\for\ x=0\to y=-2(0)+1=1\to(0;\ 1)\\for\ x=2\to y=-2(2)+1=-3\to(2;\ -3)

Look at the picture.

Answer: x = 1; y = -1 → (1; -1)

The point A = (7,4) is dilated from the origin by a scale factor r = 3. What are the coordinates of A' ?
fomenos

Given:

The coordinates of point A are (7,4).

It is dilated from the origin by a scale factor r = 3.

To find:

The coordinates of A'.

Solution:

If a figure is dilated from the origin by a scale factor k, then

(x,y)\to (kx,ky)

Here, the figure is dilated from the origin by a scale factor 3, so the rule of dilation is given by:

(x,y)\to (3x,3y)

Using this rule, we get

A(7,4)\to A'(3(7),3(4))

A(7,4)\to A'(21,12)

Therefore, the coordinates of point A' are (21,12).
