I need help finding the y-intercept of these, I am no good with slope and tables. ;-;
zubka84 [21]

Answer:

1. -4

2. 6

3. -6

(i hope this is right •_•)

Step-by-step explanation:

<u>First table</u>

When the x coordinate is 0, that point is your y intercept. For the first one, your y intercept is -4.

<u>Second table</u>

For the second one, we need to do a bit of counting. We can see the x coordinates go before and after zero, but the table does not show us 0. So, we're going to have to calculate the slope. Bear with me here, I'm a little tired and this might be rambling ;-;

So, the formula for calculating slope is \frac{y_{2} -y_{1}}{x_{2}-x_{1}}. I'm going to use those first two points to get my slope. We're going to say the first point is point 1 and the second point is point 2 (genius, i know lol). So, let's substitute in the x and y values.

\frac{9-12}{-3-(-6)}

And simplify...

\frac{-3}{3}

So, your slope is -1. We can use that. We just have to count down.

If the x is -2, the y is 8. If the x is -1, the y is 7. And if the x is 0....(drumroll please) the y is 6! So, your y intercept is 6.

<u>Third table</u>

Now, this table isn't very nice either and doesn't have an x as 0 for us. Hmpf. But we can still do what we did above. I'll just skip the explanation and you can observe my steps.

\frac{-3-(-5)}{9-3}

\frac{2}{6}

\frac{1}{3}

Let's count down....

If x = 3, y = -5

If x = 2, y = -5 1/3

If x = 1, y = -5 2/3

If x = 0, y = -6

Un carro recorre 784 kilometros en una hora expresar la rapidez en m/sg
9966 [12]

Answer:

217.7777 m/s

Step-by-step explanation:

1km = 1000 metros

784 km = 784*1000 = 784000 metros

1 hora = 3600 segundos

entonces:

784 kilómetros en una hora = 784km/h = 784000m/3600ses

= 217.7777 m /s

es decir que recorre en cada segundo:

217.7777 metros.
