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

Step-by-step explanation:

Step 1: Define

Point (4, 1.2)

Point (10, 6)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute [SF]: $\displaystyle m=\frac{6-1.2}{10-4}$
Subtract: $\displaystyle m=\frac{4.8}{6}$
Divide: $\displaystyle m=0.8$

Hi! 6 questions, find the slope of the line through the given points, ty! They should be practice questions

denis23 [38]

Answer:

3. undefined (vertical line)

4. 1

7. -4

8. 3

11. undefined (vertical line)

12. -1/3

Step-by-step explanation:

You can use the slope formula to calculate the slope which is (y2-y1)/(x2-x1)

3. (-4 - (-2)) / (6-6) denominator is 0 here so the slope is undefined (vertical line)

4. (7 - 1) / (-2 - (-4)) = 6 / 6 = 1

7. (1 - (-7)) / (2 - 4) = 8 / -2 = -4

8. (-1 - 5) / (0 -2 ) = -6 / -2 = 3

11. (3 - 0) / (-6 - (-6)) = 3 / 0 = undefined (vertical line

12. (2 - 3) / (-5 - (-2) = 1 / -3 = -1/3

1/6 Book

GalinKa [24]

Given:

$\frac{1}{6} \text{ book in } \frac{2}{3} \text{ hours}$

To find:

Number of books per hour

Solution:

We have to calculate the book read in one hour.

$\frac{1}{6}\text{ book }\rightarrow\frac{2}{3}\text{ hour}\\\\\text{we have to multiply both the side with 2/3}\\\\\frac{1}{6}\times\frac{3}{2}\text{ book }\rightarrow\frac{2}{3}\times\frac{3}{2}\text{ hour}\Rightarrow\frac{1}{4}\text{ book }\rightarrow1\text{ hour}$

Therefore, we can conclude that the answer is $\bold{\frac{1}{4}\text{ book }\rightarrow1\text{ hour }}$ which is option B.
