Answer:
54 keys
Step-by-step explanation:
If there are 6 keys on each of the nine key rings, you times 6 by 9 to get 54.
Answer:5y=x-35
Step-by-step explanation:
The given line passes through the points
,
.
Let the slope of the line be
.
If a line passes through
and
,then

So,
Y-intercept of a line is defined as the y-coordinate of the point where the line touches y axis.
Let the y intercept be 
From the graph,
The equation of the line with slope
and y-intercept
is 
So,

Answer:
There are 18 students in Grade 7, 10 are in band, so 10/18 = 0.56 are in band.
There are 12 students in Grade 8, 10 are in band, so 10/12 = 0.83 are in band.
Students in Grade 8 are more likely to be members of the band.There are 18 students in Grade 7, 10 are in band, so 10/18 = 0.56 are in band.

Answer:
slope = - 
Step-by-step explanation:
calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (3, 2 ) and (x₂, y₂ ) = (- 3, 4 )
m =
=
= -
