Find the slope first. Y2-Y1/X2-X1
-1 - -11
———
0 - -5

10
—
5

M=2

Now point slope form:
Y - Y1 = M(X - X1)

Y - 9 = 2(X - 5)
Y - 9 = 2X - 10
Y = 2X - 1

The function is f(x) = 2x - 1

I see the question last and the 4 choices first.
Look at the points you have in the table with the question.

Which vector best describes the translation below?
Nimfa-mama [501]
<h3>Answer: Choice A)  <9,0></h3>

Explanation:

Focus on one of the points in the figure on the left. Let's say we go for the upper left corner point (-7, 4)

Notice it moves to the corresponding image point (2,4). It has shifted 9 units to the right to follow the translation rule (x,y) \to (x+9, y). We've added 9 to the x coordinate, and the y coordinate stays the same.

This notation can be shortened to <9, 0>

In general, the notation (x,y) \to (x+a, y+b) is shortened to the translation vector notation < a, b >. In this case, a = 9 and b = 0.

Rewrite 3x+5y=11 and -5x+7y=9 in slope intercept form
chubhunter [2.5K]

Problem 1

subtract 3 x

5y=-3x+11

divide 5

y=3/5x+2.2'

Problem 2

add 5x

7y=5x+9

divide 7

y=5/7x+1.3'

'notice'

you can put 2.2 into a fraction (11/5) and 1.3 (9/7) if your teacher allows it, but i put them into decimals
