Which equation represents a line that passes through (5, 1) and has a slope of 1/2 ? y-5= {1/2(x-1)y-1/2 = 5(x-1)y-1=1/2(x-5)y-1= 5[x-1/2]mark this and returnsave and exitnext

Point-slope equation of this line:

.

Step-by-step explanation:

The equation for a line in a cartesian plane can take multiple forms. This question gives

The point-slope form will the most appropriate.

What is the point-slope form equation of a line ?

In general,

,

where

In other words, the point on the line.

For this line,

Thus the equation for this line:

.

y > 1/3x

y < = -x + 4

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
