Answer:

y = - 8 x + 2

Step-by-step explanation:

Use any two pairs to find the slope with

slope = (y2-y1)/(x2-x1)

for example: (0, 2), and (1, -6)

slope = (- 6 - 2) / (1 - 0) = - 8

so the equation should look like:

y = -8 x + b

use point (0, 2) to find b:

2 = - 8 (0) + b

b = 2

Then

y = - 8 x + 2

Answer:

$\frac{11}{25}$

Step-by-step explanation:

In the experiment that was conducted the coin was tossed a total of 75 times and out of those times it only landed on tails 33 times. Therefore the experimental probability of the coin landing on tails can be calculated by the dividing the times it landed on tails by the total number of times it was tossed. Like so...

$\frac{33}{75}$ or 0.44
