find the slope of the line containing the points (-1,6) and (3,5) put final.answer in slope-intercept form

Ugo [173]

Given the points (-1,6) and (3,5).

The formula to find the slope is

$m=\frac{y_2-y_1_{}}{x_2-x_1}$

Take

$x_1=-1,y_1=6,x_2=3,y_2=5$

Plug the values into the formula and find the slope.

$\begin{gathered} m=\frac{5-6}{3-(-1)} \\ =\frac{-1}{4} \end{gathered}$

The slope-intercept form is y = mx+b.

Plug the value of m.

$y=-\frac{1}{4}x+b$

ThusConsider the point (-1,6). Substitute -1 for x and for y into the equation.

$\begin{gathered} 6=-\frac{1}{4}(-1)+b \\ =\frac{1}{4}+b \\ b=6-\frac{1}{4} \\ =\frac{23}{4} \end{gathered}$

Thus, the equation of the line in slope intercept form is

$y=-\frac{1}{4}x+\frac{23}{4}$

Round 483 to the nearest ten

madam [21]

To round to the nearest ten, we will look at the number in the ones place, and determine if it is higher, lower, or equal to 5. In this case, 3 is less than 5, so we round down. This means that 483 rounded to the nearest ten is 480. :) I hope this helps you in the future! A common phrase you can think about is:
Four or less, give it a rest. 5 and above, give it a shove.

You are at a trade show where you are selling baseball cards. For $4a card and buying baseball cards for $6 a card. If you start

DerKrebs [107]

<h2>The correct option is : B) y = 200 + 4 c - 6 b</h2>

Step-by-step explanation:

Here, the given question is <u>incomplete</u>.

You are at a trade show where you are selling baseball cards for $4 a card and buying baseball cards for $6 a card. If you started the day with $200, how much money do you have at the end of the day if you sold c baseball cards and bought b baseball cards? A) 4c - 6b B) 200 + 4c - 6b C) 200 - 4c + 6b D) 200 - 2(c + b)

Here, the total number of cards sold = c

The cost of each card sold = $4

the total number of cards purchased = b

The cost of each card purchased = $6

The amount of money initially had = $200 = K

Let us assume the amount left at the end = y

So, the amount left :

= Total Money - ( Money spent on buying b cards ) + (money earned from selling c cards

The total amount earned after selling c cards at $4 each = 4 c

The total amount spent on buying b cards at $6 each = 6 b

So, the total money (y) left :

$200 + (4 c) - (6 b)

or, y = 200 + 4 c - 6 b

Hence, the correct option is : B) y = 200 + 4 c - 6 b

Find an equation that is parallel to y=5x+1 with points 5,8?

ZanzabumX [31]

Line equation:

(y - yo) = m.(x - xo)

Where (xo, yo) is a point of this line and m his angular coeficient.

To a line be parallel to other their angular coeficient needs to be equal, in a line equation (y = ax + b) the angular coeficient is "a".

So, in y = 5x + 1, a = 5. So,

(y - yo) = 5.(x - xo)

Now, just put the point coordinates in xo and yo.

(y - 8) = 5.(x - 5)

y - 8 = 5x - 25

y = 5x - 25 + 8

y = 5x - 17
