A line includes the points (9, -7) and (-6, -2). What is its equation in slope-intercept form?
Rus_ich [418]

Answer:

y=\frac{-1}{3}x-4

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

<em>m</em> - slope

<em>b </em>- y-intercept

Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Step 1: Define

Point (9, -7)

Point (-6, -2)

Step 2: Find slope <em>m</em>

<em />m=\frac{-2-(-7)}{-6-9}<em />

<em />m=\frac{-2+7}{-15}<em />

<em />m=\frac{5}{-15}<em />

<em />m=\frac{-1}{3}<em />

y=\frac{-1}{3}x+b

Step 3: Find y-intercept <em>b</em>

<em />-7=\frac{-1}{3}(9)+b<em />

<em />-7=-3+b<em />

<em />-4=b<em />

<em />

Step 4: Write linear equation in slope-intercept form

y=\frac{-1}{3}x-4

a pound of popcorn is popped for a class party. The popped corn is put into small popcorn boxes that each hold 130 popped kernel
Nostrana [21]

Answer:

12 boxes are needed

Last box contain only 20 kernels

Step-by-step explanation:

It is given that,

a pound of popcorn is popped for a class party.

The popped corn is put into small popcorn boxes that each hold 130 popped kernels.

There are 1450 kernels in a pound of unpopped popcorn.

If all the boxes are filled except for the last box,

<u>To find the number of boxes</u>

number of boxes  = Total number of kernels/Number of kernel in each box

= 1450/130 = 11 2/13

Therefore total number of boxes = 11 + 1 =12 boxes

number of kernels in 11 boxes = 11x 130 =1430 kernels

So last box contain = 1450 - 1430 = 20

Last box have only 20 kernels
