You can tell if a data set is symmetrical if when you plot the points on the graph, you can draw a line down the center, and is is the same on either side if the line. If it's asymmetrical, there is no central line.

Symmetrical is my first attachment, asymmetrical is the second :)

How do I solve without s calculator?

baherus [9]

You could solve it ( without a graph) in 2 easy ways :

1 use the equation that you have written in pencil and solve for y

y=3=-x+4
y=-x +1

Or you could use the point slop form after you find the y intercept y=mx+b

-3=4(-1)+b
b= 1

So the answer would be y= -x +1
