Answer:
(i)
y-intercept is -2
(ii)
slope is 
(iii)
slope is positive
(iv)
another point is (3,0)
Step-by-step explanation:
We are given equation as

now, we can compare it with slope intercept form of line
y=mx+b
where
m is slope
b is y-intercept
we get


So,
(i)
y-intercept is -2
(ii)
slope is 
(iii)
we can see that

is a fraction and positive
so, slope is positive
(iv)
we can select any random value of x and find y
that will give us second point
Let's assume
x=3



So, another point is (3,0)
(v)

Answer:
D. There is no association because the distribution of genre preferences is the same among the grade groups
Explanation:
Based on this graph, we can conclude that there is no association between grade and genre preference, because the distribution of genre preferences is the same among the grade groups
.
We can see that the 9th and 11th graders have a slightly higher preference for fiction than the 10th and 12th graders. However, this difference is barely noticeable and doesn't affect the conclusion. Most students from every grade prefer fiction to nonfiction, so we can conclude that the genre preference is the same among the grade groups
.
Answer:
The equivalent expression
Step-by-step explanation:
Assuming your expression is
, then we can use the power property of logarithm , which is
.
If we let a=15, b=2, and n=3
Then using the power property of logarithm will give us:

Using the power property of logarithm, the equivalent expression is 
Answer:
The equation of straight line is 3 x-y-5=0
Step-by-step explanation:
The equation of straight line having slope m = 3 and passing through the point (2,1) is
the standard form of straight line is 
now substitute m = 3 and point (2,1) is




The equation of straight line is 3 x-y-5=0
