56 is you answer you need.
Answer: y=-5x-16
Step-by-step explanation:
Since we are given the slope and the point, we can plug in the point to solve for y-intercept.
4=-5(-4)+b [multiply]
4=20+b [subtract both sides by 20]
b=-16
Now, we know the equation is y=-5x-16.
The answer is 8.72.
sqrt(76) = 2sqrt(19)
2sqrt(19) = 8.717797887
Rounded to nearest hundredth ≈ 8.72
