Draw a figure strategy a snail is at t bottom of a 10 ft wall. Each day it climbs up 3 ft. Each night it slides down back 1 ft.
antiseptic1488 [7]
The snail will reach the top of the wall by day 5.

(3ft-1ft)x = 10ft
2x = 10
2x / 2 = 10/2
x = 5 days.

The snail will reach the top of the wall on the 5th day.

11=                                                 d5
10=                                                        d5
9=                                       d4
8=                                             d4  d5
7=                          d3
6=                                d3  d4
5=             d2
4=                  d2    d3
3=  d1
2=       d1  d2
1=
0=  d1

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
