Answer:
y = -2/3x - 1
Step-by-step explanation:
Step 1: The first thing that we need to do is to find the slope of a given line
The explicit equation of a given line is: y = 3/2x + 5/2
So the slope is m = 3/2:
Step 2: The perpendicular slope (m1) is negative reciprocal of the slope m.
m1 = -2/3
So the perpendicular line will have a slope of m1 = -2/3
Step 3: Now we have a point and the slope so we can use point-slope form, which is: y - y0 = m1(x - x0)
In this example we have: m1 = -2/3, x0 = 0 and y0 = -1. After substitution we have:
y - y0 = m1(x - x0)
y - (-1) = -2/3(x - 0)
y + 1 = -2/3x + 0
y = -2/3x + 0 - 1
y = -2/3x - 1

Answer:
300 phones the company activated in one minute
As per unitary method, calculation been done to find the value of single unit from the value of multiple units.
So, she is dividing the total number of phone activated by number of minutes taken to activate to find phone activate in one minute.
Step-by-step explanation:
Here is the correct question: Meg wants to find how many phones the company activated in one minute. Explain why meg can use 15000 divided by 50 to find the answer.
As per unitary method, calculation been done to find the value of single unit from the value of multiple units.
Therefore, in the above question Meg knew the number of total phone activated by company in 50 minutes, which is 15000.
Now, she want to find how many phones the company activates in one minute.
So, she is dividing the total number of phone activated by number of minutes taken to activate to find phone activate in one minute.
Phones the company activated in one minute=
∴ 300 phones the company activated in one minute.
