Answer:
Step-by-step explanation:
<u>Equation of the line</u>
The slope-intercept form of a line is given by:
Being:
m = the slope of the line
b = the y-intercept
We can also use the point-slope form of the line:
Being:
(h,k) = A point that belongs to the line
Two lines of slopes m1 and m2 are perpendicular if:
We are given the line:
Whose slope is m1=-2
Thus, the perpendicular line has a slope of:
The required line contains the point (-8,1), thus the equation is:
Removing the parentheses:
Adding 1:

Answer:
A, B, D, E
Step-by-step explanation:
A. congruent by SAS
B. congruent by CPCTC
C. not necessarily true
D. congruent by CPCTC
E. congruent by SAS
F. not necessarily true
Answer: A, B, D, E
Function notation is a way of writing equations that has a form:
f(x)=ax+b, where x is the independent variable, f(x) is the output of the function, a and b are constants.
So if we have an equation: y-x-4=0, first we leave y on the left side and put everything else on the right side:
y=x+4, then we can write it in function notation as:
f(x)=x+4, where f(x) corresponds to y.
1,2,4,8,16,32 is the right answer
