Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 
x - 6 ← is in slope- intercept form
with slope m =
Parallel lines have equal slopes , then
y = x + c ← is the partial equation
To find c substitute (9, 2) into the partial equation
2 = 6 + c ⇒ c = 2 - 6 = - 4
y = x - 4 ← equation of parallel line
-------------------------------------------------------------------
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
= - 
, then
y = - x + c ← is the partial equation
To find c substitute (9, 2) into the partial equation
2 = - 
+ c ⇒ c = 2 + = 
y = - x + ← equation of perpendicular line
Answer:
14
Step-by-step explanation:
evaluate multiplication first
Gym a charges = 9.00
Gym b charges = 0.75
We know, Accuracy depends on number of "Significant figures", as gym a charges has only 1 s.f., it is less accurate then gym b charges which has 3 s.f.
In short, Your Answer would be Gym b
Hope this helps!
Answer:
