Step-by-step explanation:

1. convert the equation to its y = mx + b format. remember m is the slope (rise/run) and b is the y-intercept.

2. equation given: x + 2y = -6

bring x over to other side

3. now its looks like 2y = -6 - x

to get y by itself we need to divide by 2

4. now equation looks like y = -6/2 -x/2

we can reduce it so the final equation is

5. y = -1/2x - 3

this is in y=mx+b format. now its much easier to graph

6. the slope is -1/2 and the y-intercept is -3. put a point at (0,-3) and use the slope (-1/2) rise over run to get each point.

7. you move to the left because its negative

scoray [572]

Answer:

0.75 Miles

Step-by-step explanation:

To find the answer we have to find the difference in the distance the train and car travelled

65/60 is 1.083333 which is miles per minute then multiplied by 3 is 3.25 mile gone in 3 minutes

For the train it is 50/60 which is 0.833333 and the times 3 is 2.5 miles in three minutes

3.25 miles minus 2.5 miles is 0.75 miles so that is how long the train is

Katena32 [7]
Daniel spent $4.75 for a lunch and $1.85 for a snack
$4.75+$1.85=$6.6, so Daniel spent $6.6 total

Kyle spent $5.75 for lunch and $1.00 for a snack
$5.75+$1.00=$6.75, so Kyle spend total $6.75.

Final step:
$6.75-$6.6=$0.15. As a result, Kyle spent $0.15 or 15 cent more than Daniel. Hope it help!
