Answer: 2x - 7y - 40 = 0

Step by step explanation:

(-1,-6) (-8,-8)

Slope (m) = y-y/x-x

m = (-8- -6)/(-8 - -1)

m = 2/7

y-y=m(x-x). Use one of the points: (-1,-6)

y - - 6 = 2/7 (x - - 1)

y+6=2/7(x+1)

y+6=2/7x+2/7

Multiply both sides by 7

7y+42=2x+2

2x—7y-40=0

Standard form =

Answer:

y = -2x-8 ------> the equation of the line

Step-by-step explanation:

y = mx + b

8 = -2(-8)+b

  = 16 + b

-16      -16

-----------

-8 = b

y^2 - y^1 / x^2 - x^1

= 8-(-6) / -8-(-1)

= -14/7

= m = -2

Final answer: y = -2x-8

If angles A and B are consecutive interior angles, what is the measure of
n200080 [17]

Answer:

A. 105°

Step-by-step explanation:

Consecutive interior angles are angles that are supplementary, meaning they add up to 180°. If one angle is worth 75°, to find the other angle, we subtract 75 from 180 to get the angle measure.

  • 180-75
  • 105

Therefore, the answer is A.

The graph of a quadratic function has a vertex at (5,3) and goes through the point (-1,-9). What is the equation of the function
kotegsom [21]

Answer:

y=-\frac{1}{3} (x-5)^2+3

Step-by-step explanation:

We are given the following;

  • Vertex of a quadratic function = (5,3)
  • A point where the function passes through (-1, -9)

Required to determine the equation of the function;

  • We need to know the vertex form of a quadratic function is;

y=a(x-h)^2+k, where h and k correspond to the vertex (h,k)

  • Therefore, we can replace the variables h and k of the vertex in the equation;

That is;

y=a(x-5)^2+3

Then we use the equation and the point given to solve for a

x = -1 and y = -9

We get;

-9=a(-1-5)^2+3\\-9 = a(36) + 3\\-9 - 3 = 36a\\-12 =36a \\a=-\frac{1}{3}

Substituting the values of a, h and k in the equation, we get;

y=-\frac{1}{3} (x-5)^2+3

Thus, the equation of the function in the vertex form is y=-\frac{1}{3} (x-5)^2+3
