That is perfectly normal. The slope of the graph for converting inches to centimetres is not a whole number!
Any number from 0 up. Example: Whole Number: 5 Not a Whole Number: 5.5
No it isnt. The "-2" part is a whole number, but once you start tacking on more fragments and bits after the decimal point, you don't have a whole number any more.
9x is 9 on the x axis.
The slope of a line on a graph can be zero, or any positive or negative real whole number or fraction or decimal.
Then the gradient or slope is a fraction. That is no big deal.
Only if it happens to BE a whole number. As you probably know, you can't "convert" a fraction to a whole number, without losing precision. But the slope may well happen to be a whole number, such as 1, 2, 3, -1, etc. (or close enough to a whole number).
Yes. The graph of [ Y = 9x ] has a slope of 9 .

Yes, of course. If your slope is anything over 1, such as 4/1, you can also write it as 4.
The only difference is that when a slope is expressed as a whole number, ∆x (changes in x-coordinates) is always one unit.For example,m = 3 = 3/1 = ∆y/∆xm = -1/5 = ∆y/∆xm = 7/6 = ∆y/∆x
The slope of a line on a graph can be zero, or any positive or negative real whole number or fraction or decimal.
"Divide" it by 1. 35 = 35/1

Slope intercept form is y = mx + b, where m is the slope and b is the y intercept. To graph this, look at b. The number there is the y intercept. Look on the y axis on the graph and find the place where that number occurs. Plot that point, which will be (0, b). Then look at the m term. This is the slope. Imagine this number as a fraction. If it is a whole number, imagine it as the whole number divided by one. The fraction is the slope. The numerator is how far you move up or down, and the denomontator is how far you move left and right on the graph. Find the second point this way, then you can draw your line. Hope this helps!
