Use any pair of points to calculate the slope of the line.

Using the pair of points (1, 1) and (0, 0) we have calculated the slope of the line

Solution:

Given that, we can use any two points from cartesian plane,  

Let the two points be (0, 0) and (1, 1)  

We have to find the slope of the line that, passes through the chosen two points.

Now, we know that, slope of a line that passes through is given by:

Substitute these values in "m" formula,

Hence, the slope of the line that passes through (1, 1) and (0, 0) is 1.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
