Answer:
2
Step-by-step explanation:
1) if to re-write the given equation in form y=sx+i, where s - slope, i - interception, then
2) 4y=8x-9; ⇔ y=2x-2.25, then
3) the required slope is 2.
Since they are simmilar we will then have the following relationships.

Now, we solve for x, as follows:

The expression goes along the lines of. 15 is to 10 what 9 is to x, with this as was done we solve for x and determine it's value, that since they keep proportionality.
