Which formula represents calculating the slope?

question 1 options:

m = riserun

m = y2 − y1x2 − x 1

all the above

C. All of the above. Both formulas represents in calculating the slope.

Step-by-step explanation:

The slope(m) can be identified by the formula rise over run.

i.e. .

Rise is how much the line gone vertically ( y-axis) from the origin.

Run is how much the line gone horizontally (x-axis) from its origin.

∴ Rise =

And Run = .

⇒ .

Thus both equations can be used to find the slope of the line intercept.

If the points are given you can chose them yourself from the graph. Just consider any two points on the line.

homozygous. one is homozygous, while two is heterozygous.

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
