Will these help with you finding your answer??
The ordered pair is (-1,4).
(-2,2)(2,-8)
slope = (-8 - 2) / (2 - (-2) = -10/4 = -5/2
y = mx + b
slope(m) = -5/2
(-2,2)...x = - 2 and y = 2
now we sub and find b, the y int
2 = -5/2(-2) + b
2 = 5 + b
2 - 5 = b
-3 = b
so ur equation is : y = -5/2x - 3
Complete question :
A business owner wants to know if it will be profitable to open a new coffee shop in a nearby town.In towns where the shop has been successful,the shop name is recognizable to people 53% of the time .He survey random sample of 12 residents of the town. Find the probability that among these 12 surveyed residents, none of them have ever heard of the coffee shop
Answer:
0.000116
Step-by-step explanation:
Using the binomial probability relation :
Probability of success, p = 0.53
1 - p = 0.47
Number surveyed, n = 12
P(x =x) = nCx * p^x * (1 - p)^(n - x)
Probability that none has heard of the coffee shop :
P(x = 0) = 12C0 * 0.53^0 * 0.47^12
P(x = 0) = 0.000116
Point-slope form is : y-y₁=m(x-x₁)
The points given are : (8, -4)
Slope given : -5/6
So, simply plug in the values.
Remember, m = slope
y - y₁ = m(x - x₁)
y - (-4) = -5/6(x - 8)
Simplify.
y + 4 = -5/6(x - 8)
So, your answer is the THIRD choice.
