what is the slope if a line passes through the points (28,86) and (34,83)
Answer:
The slope is -0.5 or -1/2
Step-by-step explanation:
the slope of a line is easily calculated by hand using small, whole number coordinates. The formula becomes increasingly useful as the coordinates take on larger values or decimal values.
It is worth mentioning that any horizontal line has a gradient of zero because a horizontal line has the same y-coordinates. This will result in a zero in the numerator of the slope formula. On the other hand, a vertical line will have an undefined slope since the x-coordinates will always be the same. This will result the division by zero error when using the formula.

ILL MAKE MOST BRAINLIEST!!!
Given:
There exist a proportional relationship between x and y.
To find:
The equation which represents a proportional relationship between x and y.
Solution:
If there exist a proportional relationship between x and y, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex]
where, k is constant of proportionality.
We know that, proportional relationship passes through the origin because (0,0) satisfy [tex]y=kx[/tex].
For x=0, check which equation has y=0.
In option A, [tex]y=-3(0)-2=-2[/tex].
In option B, [tex]y=9[/tex].
In option C, [tex]y=4(0)=0[/tex].
In option D, [tex]y=3(0)+1=1[/tex]
Only in option C, we have a equation of the form [tex]y=kx[/tex] with 4 as constant of proportionality and it passes through (0,0).
Therefore, the correct option is C.

Jada volunteers at an animal shelter that holds picnics to introduce people to animals. For the first picnic, she brought 36 clementines for 16 people, which was the right amount. For the next picnic, there will be 40 people!
How many clementines should Jada bring for all those people? Explain or show your reasoning.
Jada would have brought 90 clementines for all those people.
What is the Ratio?The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
What is proportionality?proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.
Here,
For 40 people number of clementines be x,
So, as for the proportional relationship.
16 / 36 = 40 / x
x = 40 [36/16]
x = 10[9]
x = 90
Thus, Jada would have brought 90 clementines for all those people.

Elevation is a measure of height in relation to sea level. The highest feature on Earth is Mount Everest with an elevation +29,029 feet. The lowest feature on Earth is the Challenger Deep with an elevation -35,797 feet. What elevation does sea level represent in this scenario? Which feature is farther from sea level?
Answer:
[tex]Sea\ Level = 0\ ft[/tex]
The farthest point is the Challenger Deep
Step-by-step explanation:
Given
[tex]Highest = +29029ft[/tex]
[tex]Least = -35,797ft[/tex]
Solving (a): The sea level
Both elevations had signs in front of them.
The sea level is the point at the neutral level, neither positive nor negative.
Hence:
[tex]Sea\ Level = 0\ ft[/tex]
Solving (b): Farthest Point.
The farthest point is the one with the highest magnitude.
Comparing
[tex]Highest = +29029ft[/tex] to [tex]Least = -35,797ft[/tex]
-35,797 ft has the highest magnitude.
Hence:
The farthest point is the Challenger Deep

8x – 5y = -33
Answer:
the value of y is -3
Step-by-step explanation:
x = -6
sub -6 to the equation
8(-6) - 5y = -33
-48 - 5y = -33
-5y = -33 + 48
-5y = 15 (divide both sides by negative 5)
y = -3
Answer:
(-3)
Step-by-step explanation:
(-48) - 5y = -33
(-48) - (-33) = (-15)
(-15) / 5 = (-3)
(-48) - 5(-3) = -33

A turtle travels one half of a foot in 4 seconds. How many feet will a turtle travel in 7 seconds?
Answer: 10.5 inches or .875 feet.
Step-by-step explanation:
First calculate the SPEED = Distance /Time. So 1/2 of a foot = 6 inches so distance of 6 inches divided by time of 4 sec = s 1.5 (inches) per sec. So using Distance = speed x time we calculate 1.5in x 7 sec= a distance of 10.5 inches or 10.5 inches divided by 12in that is in a foot = .875 feet.

brainlllyy i need an answer what’s the slope of this line
Answer:
4/5
Step-by-step explanation:
The slope of the line is 4/5.
To find out the slope of a line, you must remember rise over run. Using that, you count up from whenever the line meets an actual whole number, which in this case it is -2, and then count up 4, and then you start counting right to meet the point (3, 4). The number of spaces you go to the right is 5, making the slope 4/5.
Hope this isn't too confusing and that it helps :)
