Answer:

y = -0.5x

Step-by-step explanation:

To write the equation of the line, use the formula y = mx where m is the slope. Find the slope by subtracting the x and y coordinates. Use the formula below:

m = \frac{y_2-y_1}{x_2-x_1} = \frac{2--1}{-4 - 2} = \frac{3}{-6} = -\frac{1}{2}

Since the slope is -1/2 or -0.5, this means the equation of the line is y = -0.5x.

mariarad [96]

Answer:

$6.10

Step-by-step explanation:

Given the fabric store sells the fabric for $6.97 per yard

Given that a customer buys 7/8 yard of fabric.

Let the cost the customer pays be x then

1 yard---->6.97

\frac{7}{8} yard---->x

on cross multiplication we get

x\time 1=6.97\times \frac{7}{8}

x=6.01

Therefore the amount the customer should pay is $6.01

Answer:

  5 miles

Step-by-step explanation:

It may get a bit messy, but we can solve for the desired value directly. Let d = the distance walked (in miles). Then 20-d is the distance traveled in the car. The relevant relation is ...

  time = distance / speed

The total travel time is 9:00 -6:50 = 2:10 = 2 1/6 hours = 13/6 hours. Here is the equation for total travel time.

  total time = time spent walking + time spent riding

  13/6 = (d/3) + (20-d)/30

Multiplying by 30 gives ...

  65 = 10d + 20 -d

  45 = 9d . . . . . . . . . . subtract 20

  5 = d . . . . . . . . . . . . divide by 9

The girl walked 5 miles.

_____

<em>Check</em>

Her walking time was (5 mi)/(3 mph) = 5/3 h = 1:40.

Her riding time was (15 mi)/(30 mph) = 1/2 h = 0:30.

Her total travel time was 1:40 +0:30 = 1:70 = 2:10, as required.
