Question

1. Line L mapped onto line M by a dilation centered

Answer 1

Answer:

$y = 4x - 6$

Step-by-step explanation:

The equation of line L is

$4x - y = 2$

We solve for y to get;

$y = 4x - 2$

This line is mapped onto line M by a dilation centered at the origin with a scale factor of 3.

Line M will also have the same slope as line L.

Only the y-intercept will change.

The y-intercept of L is (0,-2).

The y-intercept of M will be (0,-6) because we multiplied each by 3.

The equation of line M is

$y = 4x - 6$
