The beginning formula that you start with is y=m(x)+b
after the problem is written into the formula your ready to start.
It should look like this:
26y=-0.4(1)+b
to get the entire formula you've gotta find the
y-intercept or "b"
to start solving multiply the "m" by the "x" A.K.A:
-0.4×1
you should come up with the answer -0.4 since everything multiplied by 1 is still the same thing depending on if its positive or negative
after you've finished solving the multiplication part the equation should look slightly different like this:
26y=-0.4+b
the next step is the get "y" by itself since right now is a variable.
also you should always remember what ever process of simplifying by the same number to get rid of it in a "y=m(x)+b" equation should be done the same to the other side
take a look at the "-" sign in front of 0.4 this would mean that you are going to do the oppisite opperation to cancel it out so you would be adding the same number to either side. after adding the -0.4 to itself that would leave "b" by itself the problem should now look like this:
(26y+0.4)=b
forget about the y for now and focus on the (26+0.4)
you should get 26.4=b
insert this into the original equation of "y=m(x)+b" and this should look like this:
y=-0.4(x)+12.4
The answer to the question is B

Answer is 10:7</h3>
=======================================================
Explanation
It sounds like you want the decimal number to become a whole number. If so, then one way is to multiply both parts by 10 to move that decimal point over one spot to the right
3*10 = 30
2.1*10 = 21
The ratio 3:2.1 is equivalent to 30:21
-----
Then notice how 30 and 21 have the greatest common factor 3. Divide both parts by 3 so we can fully reduce this ratio
30/3 = 10
21/3 = 7
The ratio 30:21 simplifies fully to 10:7
The numbers 10 and 7 do not have any factors in common, other than 1, so we cannot reduce 10:7 any further.
