Answer:
he is correct because you add the exponents and then multiply 3 by itself that many times
Answer:
It will be a line passing through x=4, which will be parallel to the y-axis.
(excuse my horrible drawing skills)
A=5/12 if your solving for a
Answer:
y = -
x - 
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y + 6 =
(x - 5) ← is in point- slope form
with slope m = 
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= - 
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = -
, thus
y = -
x + c ← is the partial equation
To find c substitute (- 1, - 2) into the partial equation
- 2 =
+ c ⇒ c = - 2 -
= - 
y = -
x -
← equation of perpendicular line
