If this is 63/268 the answer is 63/268 or 0.24 rounded.
We can expand

Then using the product and chain rules,



ANSWER:
Total monthly budget in dollar = $3665.
Now,
[i] Percent of taxes,
755/3665 × 100 = 20%
[ii] Percent of housing,
790/3665 × 100 = 22%
[iii] Percent of food,
350/3665 × 100 = 9%
[iv] Percent of savings,
700/3665 × 100 = 20%
[v] Percent of transportation,
245/3665 × 100 = 7%
[vi] Percent of clothing,
110/3665 × 100 = 3%
[vii] Percent of utilities,
185/3665 × 100 = 5%
[viii] Percent of entertainment,
110/3665 × 100 = 3%
[ix] Percent of other spending,
420/3665 × 100 = 11%
Since we have two ordered pairs, we can find the slope by plugging them into (y2-y1)/(x2-x1) which translates to (3-(-6))/(-4-(-1))=9/-3=-3
Since the slope is -3, we have the equation y=-3x+b, but we don't know b. So we plug in values for x and y and solve for b.
-6=-3(-1)+b
-6=3+b
-9=b
So the y-intercept is -9 and the full equation is y=-3x-9 which means A is the only correct answer.
Hope this helped!
