Answer:

y = - x^2 + 2x + 5

= -(x^2 - 2x + 1) + 6

= -(x - 1)^2 + 6

-(x - 1)^2 always smaller or equal to 0

=> y is smaller or equal to 6

=> Option A is correct

Hope this helps!

Answer:

Question 1: Option C: y -6 = 8(x+4) is the correct answer.

Question 2: Option B: y-1=0 is the correct answer.

Step-by-step explanation:

<u>Question 1(In Picture):</u>

Given point is: (-4,6) and

Slope: m = 8

The point-slope form of equation of a line is given by:

$y - y_1 = m(x-x_1)$

Here (x1,y1) are the coordinates of the point from which the line passes. Putting (-4,6) in the equation and slope

$y -6 = 8(x+4)$

Hence,

Option C: y -6 = 8(x+4) is the correct answer.

<u>Question 2:</u>

Given point is: (3,1) and

Slope: m = 0

The point-slope form of equation of a line is given by:

$y - y_1 = m(x-x_1)$

Here (x1,y1) are the coordinates of the point from which the line passes. Putting (-4,6) in the equation and slope

$y -1 = 0(x-3)\\y-1 = 0$

Hence,

Option B: y-1=0 is the correct answer.
