Write an equation in point-slope form for each line (If possible please show work)

Hey there! :)

x = 1/2(y -3)

Step-by-step explanation:

Begin by finding the slope using the slope formula:

Plug in the coordinates:

Simplify:

Recall that point-slope form is:

Plug in the slope and coordinates into the equation:

(x - 0) = 1/2(y - 3)

x = 1/2(y -3)

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
