What is the point-slope form of an equation passing through (0, -5) with a 5 points slope of 2? *
y = 2x + 5
y + 5 = 2(x - 0)
y - 5=x-2
y = 2(x + 5)
The relationship between these two line

b. y+5=2(x-0)

Step-by-step explanation:

if we simplify that to make it look like y=mx+b it's y=2x-5.  m=2 (slope) and the b=-5 which satisfies the intercept (0,-5)

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
