Answer:
Step-The point-slope form of that line is y + 6 = -3/4(x - 2)by-step explanation:
When you have a point and the slope, you can find the point-slope form of the equation by simply putting the values in their correct spot using the base formula.
y - y1 = m(x - x1)
y - -6 = -3/4(x - 2)
y + 6 = -3/4(x - 2)
Answer:
2.73
Step-by-step explanation:
Product means the answer to the multiplication problem, where 7 and 0.39 are the factors, and you need to find the answer, which is the product. So, just multiply 7 and 0.39, and you’ll get 2.73. <u>The product of 7x0.39 is 2.73</u>

Answer:
0.333n + 28 ; 33.3 ; $41.653
Step-by-step explanation:
For the best fit line :
The slope of the graph :
Drawing a right angled triangle at any point on the best fit line :
Gradient = (y2 - y1) / (x2 - x1)
Gradient = (45 - 30) / (50 - 5)
Gradient = 15 / 45
Gradient = 0.333
Intercept :
Where best fit line crosses the y - axis = 28
b = 0.333n + 28
The extra cost of each extra call made made is the slope of the graph :
$0.333 = 33.3 cents
Estimated cost of 41 calls
b = 0.333(41) + 28
b = $41.653
Kindly note that, the values used were obtained from a graph which isn't lined, therefore values taken may not be very accurate.
