Answer:
(-2, 8) and (5, -1)
slope: (y² - y¹) / (x² - x¹)
(-1 - 8) / (5 + 2) = -9/7
y = -9/7x + b
8 = -9/7(-2) + b
8 = 18/7 + b
8 = (2.57) + b
b = 5.43
y = -9/7x + 5.43
parallel = same slope
y = -9/7x
perpendicular = reciprocated slope
y = 7/9x
Answer:
y = -x - 2
Step-by-step explanation:
The slope is -1 and the y-intercept is (0, -2).
Answer:
Alexa drove an average of 52 miles an hour (mph).
Step-by-step explanation:
First, identify what you know:
1) Alexa drove 104 miles.
2) Alexa drove 104 miles in 2 hours.
So, we need to calculate how many miles she traveled in a single hour! To do this, we simply divide the number of miles driven, by the time driven.
104 miles/2 hours = 52 mph
On average, Alexa drove 52 mph, however, this is ONLY the average. It doesn't mean she drove 52 mph the entire time. She may have driven faster for 20 minutes, and then slower for 30. 52 mph is just the average speed.
Hope this helps! :)

Answer: p = - 61/36
Step-by-step explanation: first - calculate: 36p+18+8= -35 then add the numbers we can, together : 36p+ 26= -35 then move the constant to the right: 36 p = -35 - 26, now calculate the difference: 36 p = -61 divide both sides which equals -61/36
