Draw a line representing the "rise" and a line representing the "run" of the line. State
the slope of the line in simplest form.
Answer: The slope of the line is 3/5 or 0.6
Step-by-step explanation: The line you drew was run of 4 and -1 and the rise was 7 and 4.
y=y1-y2/x1-x2
7-4/4-(-1)
7-4/4+1
3/5 or 0.6
The table below shows the height and the hand span of five students.
Which pattern of association best describes the relationship between the height and the hand span?
A. no association
B. nonlinear association
C. positive linear association
D. negative linear association
There is no association between the height and the hand span.
We can only establish an association when there is a consistent rate of increase or decrease between two variables. The increase or decrease is linear when they occur smoothly.
As we can see, we can not establish any particular relationship between the height and the hand span hence we conclude that there is no association between them.

Please Help and write the equation down as well!!
I´ll mark whoever is right Brainiest!
Answer:
y=6x+4
Step-by-step explanation:
now the formula for slope-intercept is y=mx+b
Slope (aka m) is 6
[how I got the slope is every time it goes forward 1 it goes up 6 rise/run]
so y=6x+[y intercept]
the y intercept is 4 as seen in the chart so:
y=6x+4

Dotted line:
we need to find the length of the dotted line in order to be able to calculate the area of the rectangle
radius = 8 in
diameter (dotted line)
= 8 x 2
= 16 in
(radius is half the diameter so now you know the length of the dotted line is 16 in - this answer is for the rectangle)
Area of the rectangle
A = L x W
using the 16 we found to calculate the area of the rectangle
A = 23 x 16
A = 368 in
Area of semi-circle:
Now to calculate the area of the semi-circle
A = π r² ÷ 2
A = π 8² ÷ 2
= 100.48
Adding the area of the rectangle and semi-circle together:
= 100.48 + 368
= 468.48
1dp = 468.5

What is 35% of 80?
Please answer this within half an hour, Thanks!! :D
Answer:
28
Step-by-step explanation:
35÷100×80 which will give you 28 as the answer.
Answer:
the answer is 28
Step-by-step explanation:
to get this, you would change 35% to a decimal.
to do this you would move the decimal to the right 2 times ( 35.0-----> 0.35)
then, you would multiply 0.35 by 80, and you would get 28

Which transformations were used to create a triangle JKL
The transformation used to create K'L'M' would be, dilation by a scale factor 1/2 and reflection across the x-axis.
What is transformation?"Transformations are change in the original shapes on a coordinate plane by rotation, reflection or translation. "
What is reflection transformation?"It is a transformation which produces mirror image of geometrical structure."
What is dilation?"It is a transformation in which size of the geometrical structure is changed without changing its shape."
From given diagram,
we can observe that JK = 4 and J'K' = 2
This means the size of the triangle J'K'L' is reduced by 1/2
Also, it is reflected along x-axis.
This means, the transformation used to create triangle K'L'M' would be, dilation by a scale factor 1/2 and reflection across the x-axis.
Therefore, the correct answer is option (B).

2 ?
A.5
B.-3
C.-5
D.3
Answer: C. (2, -5 )
Step-by-step explanation:
These are the coordinates of the points on the line
We can see (-3, 5) and (0, -1) on the line.
To find the y-coordinate of a point when the x-coordinate is 2, all you have to do is look for the x-intercept of 2 and look for the y-intercept.
When you look at the bottom of the graph, you can see that the x-coordinate 2 and the y-coordinate -5 intersect to form a point.
Hope that helped!
