Answer:
An equation in standard form for the line is:

Step-by-step explanation:
Given the points
The slope between two points




Writing the equation in point-slope form
As the point-slope form of the line equation is defined by

Putting the point (-2, -1) and the slope m=1 in the line equation



Writing the equation in the standard form form
As we know that the equation in the standard form is

where x and y are variables and A, B and C are constants
so


Therefore, an equation in standard form for the line is:

Answer: 
Step-by-step explanation:
Given: The total time taken by Evan to mow the 3 lawns = 
Time taken by Evan to mow the first lawn =
Time taken by Evan to mow the second lawn =
Now,Time taken by Evan to mow the third lawn =
⇒Time taken by Evan to mow the third lawn =
⇒Time taken by Evan to mow the third lawn =
Hence, the time taken by Evan to mow the third lawn = 
The answer is 5 cm for the circumference of the smaller square
Answer:
9) v= -12
10) n= -7
Step-by-step explanation:
9) v - 15 = -27
Add 15 from both sides
i.e. v - 15 + 15 = -27 + 15
v = -12
10) n + 16 = 9
Subtract 16 from both sides
i.e. n + 16 - 16 = 9 - 16
n = -7
Hope this helps!!!
