To form an equation with the given information, we use the formula :
y = mx + b, m being the slope and b being the y-intercept.
Since it is given that the slope is -9/7, we substitute m with -9/7.
y = -9/7x + b
To find b, we will substitute the known coordinates into the equation :
At point (-7 , 4), x = -7, y = 4
4 = -9/7 (-7) + b
4 = 9 + b
b = 4 - 9
b = -5
Now we know that b = -5, we will substitute b = -5 into the equation that we found earlier, y = -9/7 x + b :
y = - 9/7x - 5
To make it more readable, we can multiply the equation by 7:
7y = -9x - 5
7y + 9x + 5 = 0
-----------------------------------------------------------
Answer : 7y + 9x + 5 = 0

The answer is $17.75, though usually the taxi company will pay for gas that the driver uses.
We are given the formula r = st. We evaluate each option to know the correct answer.
A.) S = r/t
r = st
B.) t = r/s
r = st
C.) s = t/r
r = t/s
<span>D.) r = ts
</span>r = st
Therefore, the correct answer among the choice given is option C. It is not equivalent to the formula.
i think the answer is -50 but im
not sure
