We have to express the ratio 1 : 3.5 in the form p:q where p and q are whole numbers.
Consider the ratio of 1 and 3.5,
1 : 3.5 =
=
Reducing the above fraction to its lowest form.
So, we get
Therefore, the ratio 1 : 3.5 is expressed as
where 2 and 7 are the whole numbers.
2x+y=-4
5x+3y=-6
multiply first equaton by -5 and second by 2 then add them
-10x-5y=20
<u>10x+6y=-12 +</u>
0x+1y=8
y=8
the y value is 8
You use the coordinates to plug it into the equation.
Answer:
y=2x
