Answer:
y = -3x + 1
Step-by-step explanation:
Perpendicular lines have opposite reciprocal slopes, so the slope will be -3.
Plug in the slope and given point into y = mx + b
y = mx + b
-5 = -3(2) + b
-5 = -6 + b
1 = b
Then, plug in the slope and y intercept into y = mx + b again:
y = -3x + 1 will be the equation of the line
Here let's compare with slope intercept form
We get
- Slope=m=-1/3
- y-intercept=b=1
Answer:
60 people left each year so -60
Step-by-step explanation:
-300 is the total population change over the past 5 years
The population decreased.
Divide 300/5 to find the amount of people who left each year
300/5= 60
60 people left each year.
The change in the towns population is (-60)
50 = 4*12.5
500 = 4*125
There are 125 -12 = 113 numbers between 50 and 500 that are divisible by 4.
