Answer 1
Answer: Answers
1) b. -2/3
2) a. -1
3) -33/16 (no correct answer from the choices)

Explanation
The slope of a line is simply the gradient.
The gradient is the ratio of change in y to change in x.
Gradient = (y2-y1)/(x2-x1)

Question 1
Slope =((7-1))/((1-10) )=6/(-9)=-2/3

Question 2
Slope = (6.1-3.1)/(-5.5—2.5)=3/(-3)=-1

Question 3
Slope = (5/2—3)/(-5—7/3)=(11/2)/(-8/3)=-33/16

For question 3, there is no correct answer.  
Answer 2
Answer:

Answer:

The slope  of the line that passes through the pair of points (1, 7) and (10, 1) is    (-2)/(3)

The slope of the line that passes through the points (-5.5, 6.1) and (-2.5, 3.1) is -1

The slope of the line that passes through the pair of points (-7/3, -3) and (-5, 5/2) is  (-33)/(16)

Step-by-step explanation:

Formula of slope of line (m) : (y_2-y_1)/(x_2-x_1)

Part 1 : Points are (1, 7) and (10, 1)

(x_1,y_1) =(1,7)

(x_2,y_2) =(10,1)

So, using formula

Slope (m) =(1-7)/(10-1)

                =(-6)/(9)

                 =(-2)/(3)

Thus the slope  of the line that passes through the pair of points (1, 7) and (10, 1) is    (-2)/(3)

Part 2:Points (-5.5, 6.1) and (-2.5, 3.1)

(x_1,y_1) =(-5.5,6.1)

(x_2,y_2) =(-2.5,3.1)

So, using formula

Slope (m) =(3.1-6.1)/(-2.5-(-5.5))

                =(-3)/(3)

                 = -1

Thus the slope of the line that passes through the points (-5.5, 6.1) and (-2.5, 3.1) is -1

Part 3 : Points (-7/3, -3) and (-5, 5/2)

(x_1,y_1) =(-7/3,-3)

(x_2,y_2) =(-5,5/2)

So, using formula

Slope (m) =((5)/(2)-(-3))/(-5-((-7)/(3)))

                =((5)/(2)+3)/(-5+(7)/(3))

                =(-33)/(16)

Thus the slope of the line that passes through the pair of points (-7/3, -3) and (-5, 5/2) is  (-33)/(16)

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Given that;

The cost of meal and a beverage = $14

The tip = 20%

The sales tax = 6%

Now,

Since, The cost of meal and a beverage = $14

Hence, The cost for tip = 20% of 14

                                    = 20/100  x 14

                                    = $2.8

And, The cost for sales tax = 6% of 14

                                         = 6/100 x 14

                                         = $0.84

Thus, Total cost of the meal = $14 + $2.8 + $0.84

                                           = $17.64

Therefore, Total cost of the meal will be $17.64.

What is the greatest possible error if Irina measured the weight of her dog as 13 pounds?0.1 pounds
0.5 pounds
12.5 pounds
13.5 pounds

Answers

Answer:

Option B is the correct answer.

Step-by-step explanation:

Irina measured the weight of her dog as 13 pounds.

If value is 13 she rounded the values in between 12.5 to 13.49 to 13 pounds.

Maximum possible error = 13 - 12.5 = 0.5 pounds.

Maximum possible error = 0.5 pounds.

Option B is the correct answer.
