Y = mx + b
M= your slope or rise over run
B = your y-intercept
For example if the rise was 5 and the run is 6, the equation would say
y = 5/6 + b
The / being your fraction bar
The y-intercept is where your line crosses the y-axis
So say that the line crosses the y-axis at 10
y = 5/6 + 10
That about sums it all up!
2x4=8 2x2=4 4+8=12, so it is A
Answer:

Step-by-step explanation:
I got it right on edge
Answer:
$41.25
Step-by-step explanation:
We can use this formula to solve this problem:
s
=
p
−
(
d
×
p
)
Where:
s
is the sales price: what we are solving for in this problem.
p
is the original price: $55 for this problem.
d
is the discount rate: 25% for this problem. "Percent" or "%" means "out of 100" or "per 100", Therefore 25% can be written as
25
100
.
Substituting and calculating
s
gives:
s
=
$
55
−
(
25
100
×
$
55
)
s
=

13.75
s
=
