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
-----------------------------------------------------------
(-3,4)(0,-3)
slope = (-3 - 4) / (0 - (-3) = -7/3 <=
The answer would be s=-60
Answer:
89 meters per second.
Step-by-step explanation:
That is quite fast!
First, we are given that in 9 sec our falcon has flown 801 meters, let's write an equation for that:
9s = 801
So in order to get s, we divide each side by 9.
Solve!
s = 801/9
s = 89
