Answer:

Step-by-step explanation:

1) point slope form is:

y-y1=m(x-x1)

y1=8

x1=4

m=(slope)

to find m: y2-y1/x2-x1

hence

-2-8/2-4=-10/-2=5

m=5:

y-8=5(x+4)

Eddi Din [679]

Answer:

Step-by-step explanation:

12+x+10=480

22+x=480

x=458

2(12)+2(x+10)=480

24+2x+20=480

44+2x=480

2x=436

x=218

Identify the translation of the figure with the vertices F(4,0), G(1,3), H(2,6) and I(4,2), along the vector ⟨−4,−4⟩. HELP PLEAS

mr Goodwill [35]

Answer:

the last choice shown here: F'(0, -4), G'(-3, -1), H'(-2, 2), I'(0, -2)

Step-by-step explanation:

The translation vector tells you that the new coordinates are found by adding -4 to each of the old coordinates. When you realize that the answer choices differ in their values for H' and I', you can conclude that you only need to find one of those to determine the correct answer.

H' = H + (-4, -4) = (2-4, 6-4) = (-2, 2) . . . corresponds to the last choice shown

_____

When you subtract 4 from each of the coordinates of the other points, you find they also match the last answer selection.
