If the line y-7=3(x+5) is dilated with a center at the origin and a scale factor of 4, which of the following equations would describe its image?

If the line y73x5 is dilated with a center at the origin and a scale factor of 4 which of the following equations would describe its image class=

Respuesta :

When we dilate a line with a scale factor of "a", we change its equation by changing the slope.

The slope gets multiplied by "a".

In the equation given, the slope is "3". After a dilation with a scale factor of 4, the slope would become:

3 * 4 = 12

The equation, after dilation, would be:

[tex]y-7=12(x+5)[/tex]
