Answer:

m=-3

General Formulas and Concepts:

<u>Pre-Alg</u>

  • Order of Operations: BPEMDAS

<u>Alg I</u>

  • Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Step-by-step explanation:

<u>Step 1: Define</u>

Point (2, 6)

Point (1, 9)

<u>Step 2: Find slope </u><em><u>m</u></em>

  1. Substitute:                    m=\frac{9-6}{1-2}
  2. Subtract:                       m=\frac{3}{-1}
  3. Divide:                           m=-3

Answer:

-3

Step-by-step explanation:

The equation for the slope is the change in y/ the change x.

In order to find the change in y we have to subtract the second y (9) by the first y(6) and do the same for x.

That will be (9 - 6)/(1 - 2) = 3/-1 = -3

Slope is -3

Graph f(x)=−3/4x−4 . Use the line tool and select two points to graph the line.
lions [1.4K]

Answer:

Two points on the line would be (0, -4) and (4, -7)

Step-by-step explanation:

In order to find this, we can start at the y-intercept. The y-intercept is the constant at the end of the equation. In this case it is -4, which gives us the first point of (0, -4).

We can find the second point by using the numerator of the slope to determine how much we go up or down (-3) and the denominator for how much we go left to right (4). So we add the 4 to the x value and add the -3 to the y value.

(4, -7)

Suppose y varies directly as x write a direct variation equation that relates x and y
Oksana_A [137]

Answer:

y=2/3x

Step-by-step explanation:

A direct variation equation is y=kx. if k=2/3, then if x was 9,y would be 6.

Given the equation 4x2 − 8x + 20 = 0, what are the values of h and k when the equation is written in vertex form a(x − h)2 + k =
GenaCL600 [577]

Answer:

The correct option is:

h = 1, k = 16

Step-by-step explanation:

y=4x^2-8x+20 =0

It is a quadratic formula in standard form:

ax^2+bx+c

where a = 4 , b = -8 and c=20

The vertex form is:

a(x − h)2 + k = 0

h is the axis of symmetry and (h,k) is the vertex.

Calculate h according to the following formula:

h = -b/2a

h= -(-8)/2(4)

h = 8/8

h = 1

Substitute k for y and insert the value of h for x in the standard form:

ax^2+bx+c

k = 4(1)^2+(-8)(1)+20

k = 4-8+20

k=-4+20

k = 16

Thus the correct option is h=1, k=16....
