Write an equation relating the variables in each table
time(x) 1 2 4 6
distance(y) 15 30 60 90

Step-by-step explanation:

Let

x ----> the time

y ----> the distance

we have the points

Find the slope m

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

take the points

substitute in the formula

Find the linear equation in point slope form

we have

substitute

---> equation in point slope form

Convert to slope intercept form

Verify for x=2

----> is ok in the table

Verify for x=4

----> is ok in the table

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
