Marisol attempted to determine the slope of a line based on the two points shown in the table below.

x
y
–1
4
3
10

Step 1: (–1, 4) and (3, 10)

Step 2: StartFraction 10 minus 3 Over 4 minus (negative 1) EndFraction

Step 3: StartFraction 7 Over 5 EndFraction

Which statement best explains Marisol’s error?
a. Marisol computed StartFraction y 2 minus y 1 Over x 1 minus x 2 EndFraction.
b. Marisol computed StartFraction x 2 minus x 1 Over y 2 minus y 1 EndFraction.
c. Marisol computed StartFraction y 2 minus x 2 Over y 1 minus x 1 EndFraction.
d. Marisol computed StartFraction x 2 minus y 2 Over x 1 minus y 1 EndFraction.

step-by-step explanation:

1+1=2

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

felicia:

260 words per minute

200< 260 < 265
