Answer:

y=4x-2

Step-by-step explanation:

for every 1 unit increase in x, y values change by a factor of four units

slope=4x

f(x)=y

y=mx+b

2=4(1)+b

b=-2

equation= y=4x-2

CHECK

6=4(2)-2

6=8-2

6=6

CORRECT

10=4(3)-2

10=10

CORRECT

alternatively... (y2-y1)/(x2-x1)

(6-2)/(2-1)= (4)/(1)

slope=4

What is the simplest way to explain scale drawings for middle school math?
Allushta [10]

Answer:

The simplest way to teach middle school math scale drawings is to use real pictures to relate to each other to explain the concept. For example, scaling a red ball of 1" to a ball of 2" and so on. This will show how the ball increases by size by adding 1" each time.

What are the factors of the quadratic function graphed below. Please show work , please help
dlinn [17]

Answer:

x and (x - 6)

Step-by-step explanation:

y = a(x - h)² + k

h = 3    k = -2

y = a (x - 3)² -2

For point (0 , 0) on the function

0 = a (0 - 3)² -2

0 = 9a - 2

a = 2/9

a (x - 3)² -2 = 2/9 (x² - 6x + 9) - 2 = 2/9 * x * (x - 6) + 2 - 2 = 2/9 * x * (x-6)
