Answer:

The answer is the second rule: (x,y) --> (x+8, y+2).

Step-by-step explanation:

If you look at a graph, positive "x" is to the right, and negative "x" is to the left. Positive "y" is up, and negative "y" is down. Knowing this, if the problem is asking you how to describe moving 8 units to the right and 2 units up, then you know that it wants both a positive "x" and a positive "y".

a line is perpendicular to y - 5 = -1/4(x + 8) and goes through the point (-1,2). What is the lines y-intercept?

lisabon 2012 [21]

Answer:

y = 4x + 6

Step-by-step explanation:

Turn the equation we are given into slope-intercept form.

y - 5 = -1/4(x + 8)

y - 5 = -1/4x - 2

y = -1/4x + 3

The slope of a perpendicular line is the opposite reciprocal of the original line.

-1/4 -> 4/1 -> 4

Find the new y-intercept using the point given.

y = 4x + b

2 = 4(-1) + b

2 = -4 + b

6 = b

Fill in everything we solved for.

y = 4x + 6

Best of Luck!

Consider the function f(x) = -4x²-9x+20. Determine f(-2)=

hoa [83]

Step-by-step explanation:

you just substitute (-2) into the x values of the above function

$f( - 2) = - 4( - 2)^{2} - 9( - 2) + 20 \\ f( - 2) = 22$
