Answer:
3.81 = 3 81/100
Step-by-step explanation:
This can’t be simplified so it stays as 3 
Options :
y – 8 = –0.15(x – 10)
y + 8 = –0.15(x – 10)
y – 8 = –0.2(x + 10)
y + 8 = –0.2(x – 10)
Answer:
y – 8 = –0.2(x + 10)
Step-by-step explanation:
(-10, 8)
General equation in point - slope form:
y - y1 = m(x - x1)
m = slope
Given the points : ( - 10, 8)
x1= - 10 ; y1 = 8
y - y1 = m(x - x1)
Substitute the values of x and y into the equation :
y - 8 = m(x - - 10)
y - 8 = m(x + 10)
The best option which fits is :
y – 8 = –0.2(x + 10)
Answer:
b
Step-by-step explanation:
Step-by-step explanation:

While subtracting , the sign of each term of second expression changes & remove the parentheses.
⟶ 
Combine like terms. Like terms are those which have the same base. Only coefficients of like terms can be added or subtracted.
⟶ 
⟶ 
In standard from , the expression should be written in such a way that the power of variables goes from highest to lowest.
