It makes the addition easier if you combine like terms like the two 1/2s and then make them all have the denominator of 12 (changing the numerators to equal it out)

D=-3\qquad \textit{vertically down-shifted by }3$

NO LINKS I NEED REAL ANSWERS <br> what are the 2 missing numbers on the blanks?

zavuch27 [327]

Answer:

Step-by-step explanation:

P1 = (2000, 1000) in the form (x1,y1)

P2 = (2012, 3400) in the form (x2,y2)

m = (y2-y1 / x2-x1)

m = ( 3400-1000 ) / (2012 - 2000)

m = 2400 / 12

m = 200

y = 200x + 800
