You know that you can spot the slope and intercept right away
IF you 'solve' the equation for 'y'. Then you'll have
y = (slope) x + (intercept) .
So for choices 'A' and 'B', you have to massage the equation
into the standard form, and then just look at it and see whether
the slope is 9/4 and the intercept is -14.
A). -9x + 4y = -56
Add 9x to each side: 4y = 9x - 56
Divide each side by 4 : y = 9/4 x - 14 <== Yes ! Good one.
B). 9x + 4y = 56
Subtract 9x from each side: 4y = -9x + 56
Divide each side by 4 : y = -9/4 + 14 <= no, signs are wrong
C). Yes. Slope is 9/4 and intercept is -14 .
D). No. Slope is 9/4 alright, but intercept is +14, not -14 .

Answer:
1 5/6
Step-by-step explanation:
We first convert each mixed number to an improper fraction.
To change -6 7/8, we will ignore the negative at first. Multiply the whole number by the denominator:
6(8) = 48
Add the numerator:
48+7 = 55
Putting the negative back in, we have -55/8.
To change -3 3/4, ignore the negative at first. Multiply the whole number by the denominator:
3(4) = 12
Add the numerator:
12+3 = 15
Putting the negative back in, we have -15/4.
This gives us
-55/8 ÷ -15/4
To divide fractions, flip the second one and multiply:
-55/8 × -4/15
Multiply straight across:
(-55×-4)/(8×15) = 220/120
Simplifying this, we know that both 220 and 120 are divisible by 10; this gives us
22/12
Both 22 and 12 are even, so they are both divisible by 2. This gives us
11/6
6 will go into 11 one time, with 5 remaining; this gives us
