Write two point-slope equations for the line passing through the points (6, 5) and (3, 1). Show your work.
NikAS [45]

Answer:

y=-4/3x-3

Step-by-step explanation:

You look for the slope using the the slope formula (m=y2-y1/x2-x1)

You will end up with (m=1-5/3-6)

Simplify to end up with (-4/3) as your slope.

Then, pick a coordinate point. Your choices are (6,5) and (3,1). You will us it to plug into the equation.

I am picking (3,1) The y-value here is 1 and the x-value is 3.

Your equation to find b, or the y-intercept is going to be (1=-4/3(3)+b)

You will have to simplify.

1=-4/3(3)+b

You will multiply -4/3 and -3 and end up with 4 so it looks like...

1=4+b

You subtract 4 on both sides and then end up with....

-3=b

So, the final answer is: y=-4/3x-3

David is making his own strawberry yogurt. In his mixture, the number of strawberries is proportional to the amount of milk in c
ratelena [41]
To determine the amount of milk that David should be adding, we need to generate and expression that would relate the number of strawberries and the number of cups. From the problem statement, it is said that the number of strawberries is directly proportional to the number of cups of milk. We write it as:

X α Y        where X represents the number of strawberries and Y represents the number of cups of milk

To get rid of the proportionality sign, we introduce a proportionality constant k. We calculate this by using the initial conditions given.

X = kY

at X = 14 strawberries Y = <span>2 1/2 cups of milk = 5/2 cups
14 = k(5/2)
k = 28/5

At X = 203

X = kY
203 = 28/5 (Y)
Y = 145/4  or 36 1/4 cups of milk needed</span>

How to erite a sequence of 1/4 , 1/2,3 write a rule for the sequence 1/4 1/2 3/4
FrozenT [24]
The equation for finding the equation of an arithmetic sequence is an=a1+(n-1)d, where n is the input for the sequence, a1 is the first term, and d is the difference between each term. 

a1= 1/4
d= 1/4 

an= 1/4 + (n-1)(1/2) - First you need to distribute the 1/2 to both the n and -1 to get:    an= 1/4 + 1/2n -1/2.

Then you need to add like terms (1/4-1/2) to get an=1/2n-1/4.  Hope this helps!
