What is the slope of the line that passes through (3'-7)(-1'1)

Answers

Answer 1
Answer:

Answer:

Slope of line passing through (3,-7) and (-1,1) = -2

Step-by-step explanation:

The slope of a line passing through points (x₁,y₁) and (x₂,y₂) is given by (y_2-y_1)/(x_2-x_1)

Here points are given by (3,-7) and (-1,1)

So we have (x₁,y₁) = (3,-7) and (x₂,y₂) = (-1,1)

Slope =(1-(-7))/((-1)-3)=(8)/(-4) =-2

Slope of line passing through (3,-7) and (-1,1) = -2

Answer 2
Answer: To solve for slope. Remember that slope, m= (change in y)-(change in x). So that means m= (y2-y1)/(x2-x1). Putting in the values we get (1--7)=(1+7)/(-1-3)= (8)/(-4)= -2. So m, or slope is -2.

The probability that a city bus is ready for service when needed is 77%. The probability that a city bus is ready for service and has a working radio is 65%. Find the probability that a bus chosen at random has a working radio given that it is ready for service. Round to the nearest tenth of a percent. (Hint: Divide)

Answers

Answer:

0.84

Step-by-step explanation:

Let the probability that a city bus is ready for service when needed is represented as P(ready)=77%=0.77

Let the probability that a city bus is ready for service and has a working radio be represented as P(ready and radio)=65%=0.65

probabilty that it has a working radio given that it is ready for service =

P(radio and ready)=P(ready and radio) ÷  P(ready)

=0.65÷0.77=0.84416

≈0.84 to the nearest tenth

Is 5 - (-3) equal to 8 or -2. And if one or the other, please state why one is correct and the other isn't.

Answers

8

two negatives make a postive as they cancel each other out

5 - - 3 = 5 + 3 = 8

the only way the answer could be - 2 is if the original question said 5 + - 3 = - 2

In the attachment, the points are listed in the order given in the problem statement. (They are listed to the right of the "rotation matrix", with x-coordinates above y-coordinates.)

I really don't like to do repetitive calculations, so I try to use a graphing calculator or spreadsheet whenever possible. Angles are measured CCW.

As always, the rotation transformations are ...

  180° — (x, y) ⇒ (-x, -y)
