Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Step-by-step explanation:

<u>Step 1: Define</u>

y-intercept (0, 5)

Point (1, 2)

<u>Step 2: Find slope </u><em><u>m</u></em>

Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>

  1. Substitute [SF]:                    m=\frac{2-5}{1-0}
  2. Subtract:                              m=\frac{-3}{1}
  3. Divide:                                 m=-3

<u>Step 3: Write Equation</u>

<em>Plug in variables into the general form.</em>

keisha is reading a 325 page book at a rate of 25 pages per day. use a point slipe equation to determine whether she will finish
Mademuasel [1]
You can easily tell if Keisha will finish reading the book by this equation:

y = 325 - 25x
where y is the number of pages left, and x is the number of days. A point slope for has a standard form of y - y1 = m(x - x1). Thus, we arrange it in this manner:

y = 25(13 - x)

Then, substitute x = 10:

y = 25(13 - 10)
y = 75

So, Keisha will not be able to finish the book in 10 days. There are still 75 pages left to read.

Jay's mean score for four quizzes is 99. ​ ​His scores for the first three quizzes are 88 , 55 , and 99. ​ ​What is Jay's score
Katarina [22]

Answer: 154

Step-by-step explanation:

The mean is calculated by adding up all the numbers and dividing by the number of observations added up.

The above can therefore be expressed as:

(88 + 55 + 99 + x) / 4 = 99

242 + x = 99 * 4

242 + x = 396

x = 396 - 242

x = 154
