2 3/2 is not equal to any of these
X < 12 its actually very simple , just see that the x is on one side and nothing can be moved
Here the line passes through (0,0) and (1,3).
First we need to find the slope , and for that we need to use the following formula

On substituting the values from the point, we will get

Now we will use slope intercept form, which is

Where m is the slope and b is the y intercept
And on substituting the values of x and y from the point (1,3) and slope, m = 3, we will get


b =0
Substituting the values of m and b in the slope intercept form, we will get

The expression for five groups of a number added to seventeen.
Let the number be X
Five groups of the number will be 5X
The required expression will be
5(X) +17
