Answer:

-2

Step-by-step explanation:

slope: (y² - y¹) / (x² - x¹)

(-1 - 1) / (1 - 0) = -2 / 1 = -2

y = -2x + b

plug in an (x, y) value to find b

1 = -2(0) + b

1 = -2 + b

b = 3

y = -2x + 3

rate of change is -2

How would you find the slope of the line containing the points P(4, 9) and R(57, 73)?
nydimaria [60]

Answer:

Slope is defined as the difference in the vertical axis divided by the difference in the horizontal axis, going left to right (s = dy/dx).  P has a lesser x co-ordinate, so it will be R - P in this case, giving us (ry - py) / (rx - px):

s = \frac{{\Delta}y}{{\Delta}x}

s = \frac{73 - 9}{57 - 4}

s = 64/53

The diffrence between an integer p and (-5) is 1 find the value of p ​
Nastasia [14]

Solution:

<u>Note that:</u>

  • Given sentence: The difference between an integer p and (-5) is 1.

<u>Let's reread the sentence carefully.</u>

The difference between an integer p and (-5) is 1.

  • => p - (-5) = 1

<u>Change the sign.</u>

  • p - (-5) = 1
  • => p + 5 = 1

<u>Subtract 5 both sides:</u>

  • p + 5 = 1
  • => p + 5 - 5 = 1 - 5
  • => p = -4

A distribution has a mean of 16 and a standard deviation of 6. What is the Z score that corresponds with 34?
Brrunno [24]

Answer:

Z = 3

Step-by-step explanation:

In a normal distribution, the Z score that corresponds with a data point x is calculated using the formula;

Z=\frac{x-mean}{standard deviation}

For the case given, the z score will be;

Z=\frac{34-16}{6}=3
