Choice D : look at where you think the line would be if it followed the direction of the data so that about half of the points fell above the line and half below. The two most important things to note are the slope of the line and y intercept.
This is a negative relationship as the line falls as you read it from left to right. That eliminates choice C. Next, it appears the line of best fit would have a y intercept around 10 on the y axis and then fall down and to the right cutting the data. Note that choices A and B have y intercepts that don't make sense for the data. Choice D does have a y intercept of 10 and a negative slope.

Answer:

Catherine is not correct (see the explanation)

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

the two points from the graph are

(4,40) and (7,70)

substitute the values in the formula

$m=\frac{70-40}{7-4}\\m=\frac{30}{3}\\m=10$

therefore

A car traveled for 6 hours on one highway and for 2 hours on a second highway. If the total distance traveled was 488 miles, and

Nataly [62]

6V + 2(V+12) = 488
8V = 464
V = 58 mph for 6 hours

V+12=70 mph for 2 hours.

check: 58*6 = 348

70*2 = 140

348 +140 =488

the car was traveling at 70 mph on the 2nd highway

(d) Jim walks three miles in 45 minutes. How long does it take for him to walk 5 miles?

kramer

Answer:

5 miles = 75 minutes

Step-by-step explanation:

<u>We know that:</u>

3 miles = 45 minutes

<u>Solution:</u>

3 miles = 45 minutes
=> 1 mile = 45/3 minutes
=> 5 miles = 45/3 x 5
=> 5 miles = 15 x 5
=> 5 miles = 75 minutes

Hence, it takes 75 minutes for Jim to walk 5 miles.
