Answer:
y = 3x -1
Step-by-step explanation:
When the given points are dilated by a factor of 1/5 about the origin, each of the coordinate values is multiplied by 1/5. The points after dilation are ...
... (2/5, 1/5), (-1/5, -8/5)
The line through these points can be found starting with a 2-point form of the equation for the line.
... y -y1 = (y2 -y1)/(x2 -x1)·(x -x1)
Filling in the point values gives ...
... y -1/5 = (-8/5 -1/5)/(-1/5 -2/5)(x -2/5)
... y = (-9/5)/(-3/5)(x -2/5) +1/5 . . . . simplify parentheses, add 1/5
... y = 3x -1 . . . . . simplify
_____
The graph shows the original points and the line through them in red, and the dilated points and line in green.

Step-by-step explanation:
Answer:
infinite solutions along the line -3x+y = 6
Step-by-step explanation:
9x -3y = -18
-3x + y = 6
Multiply the second equation by 3
3( -3x+y) = 3*6
-9x +3y = 18
Add this to the first equation
9x -3y = -18
-9x +3y = 18
------------------------
0 + 0 = 0
This means it is the same line which means there are infinite solutions along the line -3x+y = 6
