Which equation below has a slope of 5 an dpasses through the point (9, - 7) Ob y + 7 = 5(x - 9) y - 9 = 5(x - 7) y - 5 = 7(x - 9) y - 7 = 5(x + 9) Od

The point-slope formula states: (y−y1)=m(x−x1). Where m is the slope and (x1y1) is a point the line passes through. ... (y−97)=57(x−35)

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
