I'm learning about graphing proportional relationships

To solve for slope we want to use the formula (y2-y1)/(x2-x1)

We can use any two points on the graph to solve for the slope, so you can choose at random. 

The points we'll use are (2,1.2) and (0,0)
We can then plug the values into the formula

(0-1.2)/(0-2)

1.2/2=.6

So the slope of the graph is .6x

y=.6x

Rounding decimals is very similar to rounding other numbers. if the hundredths and thousandths places of a decimal is forty-nine or less, they are dropped and the tenths place does not change. for example, rounding 0.843 to the nearest tenth would give 0.8. , your welcome !
