Give the variation equation described in each situation. Use k for the constant.uppose you are driving. You notice that after driving for 3 hours, you are 225 miles from Seattle. You continue driving, and calculate that after driving 6 hours you are 435 miles from Seattle.

00:01 So we have lots of tasks here for this question.

00:03 We're given this equation where y is the distance from los angeles is equal to 62x, where x is the number of hours driven.

00:16 So we need to complete the table of values and write down the information as orders pair, as ordered pairs.

00:22 You said the table can't be copied, but i imagine, let me just draw out a table for you.

00:28 I imagine what the values will be, will be something like x, y, and it'll be like one hour, two hour, three hour, four hour, five hour.

00:40 All we do is sub these values of x into the equation.

00:45 So 62 times one is obviously 62.

00:47 So this is going to be in hours and this is going to be in miles.

00:53 It doesn't say.

00:56 But i'm going to assume miles.

01:00 So this will be 62 miles the next one will be 124 miles the next one will be 248 miles the next one will be 496 hours the next one will be 992 hours and so on and there might be say you know 1 .5 hours or whatever and that would be obviously just 62 times 1 .5 you can work that out so then it says label a coordinate system choose an appropriate scale and graph the ordered pairs so i'm obviously not going to be drawing out a whole graph here i'm just going to be showing you how to do it at zero we've driven zero miles at one hour we all have driven so this is time in hours this is distance so not time this will be x and hours and this will be y in miles so let's say we have one hour two hours three hours four hours and five hours and here let's say we had 100 200 300 300 400 500 600 600 600 700 600 700 um, 800.

02:36 In fact, i've noticed a massive mistake i've done here.

02:39 Sorry, this shouldn't be like that.

02:41 This should obviously just be 62 times 3, which is 186.

02:46 And then 60.

02:47 I'm so sorry about that.

02:48 That wasn't my mistake.

02:48 I just got lost in the clouds there.

02:51 Um, 124 and therefore 62 times 5 is 310.

02:56 So we don't need all of these.

02:58 So let me just get rid of them.

02:59 I actually got rid of the axis.

03:08 So we're going to go up to just over 300.
