Answer:
slope = -
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 )
Rearrange - 9x - 6y = 18 into this form
Add 9x to both sides
- 6y = 9x + 18 ( divide all terms by - 6 )
y = - x - 3 ← in slope- intercept form
with slope m = -
Answer:
constant of variation = 3
Step-by-step explanation:
we know that b varies jointly with c and d
so:
b∝c∝d
and b varies inversely with e, so
b∝
and i will call the constant of variation k, this way we can make an equation for b in the following form:
this satisfy that b varies jointly with c and d (if b increases, c and d also increase) and inversely with e (if b increases, e decreases)
we know that when b is 18, c is 4, d is 9, and e is 6:
substituting this in our equation for b:
and we solve operations and clear for the constant of variation k:
the constant of variation is 3.
