In the linear equation: 8x - 2y = 16, the slope of this line is

x - y = 1

Step-by-step explanation:

by divided by two on both sides then dividing by 8 on both sides and we are left with x - y = 1

 Y = 4x-8

Step-by-step explanation:

use photomath

move 8x to the right -2y=16 -8x

change signs 2y=-16+8x

divide both sides of the equation by 2

y= -8 +4x

Use the communicative property to reorder the terms

Y=4x-8

The last graph.

Step-by-step explanation:

In the first graph, the darker triangle has one side that is 1/3 of the corresponding side of the other triangle, and one side that is 2/5 of the corresponding side of the other triangle.  This is not proportional for all sides, so this is not a dilation.

In the second graph, the darker triangle has one side that is 1/2 of the corresponding side of the other triangle, and one side that is 3/5 of the corresponding side of the other triangle.  This is not proportional for all sides, so this is not a dilation.

In the third graph, the darker triangle has one side that is 1/3 of the corresponding side of the other triangle, and one side that is 1/2 of the corresponding side of the other triangle.  This is not proportional for all sides, so this is not a dilation.

In the fourth graph, the darker triangle has one side that is 2/3 of the corresponding side of he other triangle, and another side that is 4/6=2/3 of the corresponding side of the other triangle.  Since these are both right triangles, this means the other side, the hypotenuse, will have the same ratio.  Since it is proportional for all sides, this is a dilation.
