Answer:

y = -5x - 21

Step-by-step explanation:

Given in the question,

equation of a parallel line

y = -5x + 6

point through which it passes

(-4,-1)

Step1

Find the gradient of the equation given, as it is parallel so it will have same gradient

equation of straight line

y = mx + c

where m is gradient

            c is y intercept

y = -5x + 6

m =-5

Step2

Find y-intercept

-1 = -5(-4) + c

-1 = 20 + c

c = -20 - 1

c = -21

Step3

form the equation

y = -5x - 21

Answer:

y=-5x-21

Step-by-step explanation:

The given line has equation;

y=-5x+6

This line is in the form  y=mx+c, where m=-5

(x_1,y_1)=(-4,-1)

The required equation can be found using the formula;

y-y_1=m(x-x_1)

We substitute the given point and slope to get,

y+1=-5(x+4)

Expand

y=-5x-20-1

y=-5x-21

Thank you will mark brainliest

Answer:

Option D

Step-by-step explanation:

We have to find the value of the composite function (h o k)(2).

Since, (h o k)(x) = h[k(x)]

(h o k)(2) = h[k(2)]

From the picture attached,

At x = 2

k(2) = (-2)

Therefore, h[k(2)] = h(-2)

Since, h(x) = \frac{3}{x+1}

Therefore, h(-2) = \frac{3}{-2+1}

                          = -3

(h o k)(2) = -3 is the answer.

Option (D) is the correct option.
