Find the slope question 2 options: -4/3 -3/4 4/3 3/4

Find two points on the line that cross the X and Y at whole numbers to make it easier.

The line cross at (0,1) and (-4,-2)

The slope is the change in Y over the change in x:

Slope = (1-(-2)) / (0-(-4))

Slope = 1+2 / 0+4

Slope = 3/4

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
