A line passes through the point (2,-6) and has an initial value of 6. What is the rate of change for this line?
A. -12
B. -6
C. -1/6
D. 6

Answers

-6
Just did the question

-6

We assume "initial value" means the y-intercept is (0, 6). The rate of change is the "rise" divided by the "run" between the two points.

rise = -6 -6 = -12 . . . . difference of y-values

run = 2 -0 = 2 . . . . . . difference of corresponding x-values

rate of change = rise/run = -12/2 = -6

The rate of change of this line is -6.

lexi bought 1 2\5 pounds of green grapes and 2 3\10 pounds of red grapes. Grapes are 2.99 a pound. Did lexi spend more or less than $12 on grapes? please explain asap

Answers

Answer:

Less than $12

Step-by-step explanation:

I changed everything into decimals to make it easier to solve:

1 2/5= 1.4

2 3/10= 2.3

1.4+2.3=3.7

2.99·3.7=11.063 (Round it to the nearest hundredth and you get 11.06)

Less than $12

Given the two points (3, -1) and (5,3), explain how to write the equation of the line in slope intercept form.


*Calculate Slope first

*Calculate y-intercept second

*Write your answer in the form y=mx+b (HINT: you will need to find m and b)


Help quickly!!! I will give brainylist or whatever

Answers

Can you add an image please?

1. To find slope use the slope equation which would be (3 - -1)/ (5-3). The slope is m = 4\2 which is m = 2

2. Plug in one of the points to find the y-intercept. Using the point (5,3) , you would plug this point into the slope intercept equation, along with the slope which was found. 3= (2 x 5) +b. Solving this equation b=-7

3. The slop intercept form is y = 2x - 7


I hope this is the right answer!

Roni wants to write an equation to represent a proportional relationship that has a constant of proportionality equal to Start Fraction 7 over 25 End Fraction. She writes the equation y = x + Start Fraction 7 over 25 End Fraction. What error is Roni making?

A. She should have written y = negative x + StartFraction 7 over 25 EndFraction so that x and y have a constant sum.

B. She should have written x y = StartFraction 7 over 25 EndFraction so that x and y have a constant product.

C. She should have written y = StartFraction 7 over 25 EndFraction x so that x and y have a constant quotient.

D. She should have written y = StartFraction 7 over 25 EndFraction so that y has a constant value.

1). the submarine is descending 100 feet per minute. this is because the line decreases 100 on the y axis when the x axis increases by 1.
2). the submarine is descending 50 feet per minute. this is because the line decreases 50 on the y axis when the x axis increases by 1.
3). y=15x this is because the slope increases by 15 on the y axis when 1 is increased on the x axis. the y intercept is 0. this means that every hour of piano lessons they get paid $15.
