Writing a Linear Equation Given Two Points Write a linear equation for the line that passes through the given points.

y=-3x+5

Step-by-step explanation: y=mx+b

to find slope (m) use the equation

so

= -3

to find b

use y=mx+b

-1=-3(2)+b

-1=-6+b

5=b

Hope this helps :)

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
