3. A line passes through (9, -9) and (10,-5). a. Write an equation for the line in point-slope form.
b. Rewrite the equation in standard form using integers.
A y + 9 = 4(x + 9); -4x + y = -45
B y + 9 = 4(x - 9); - 4x + y = -45
Cy - 9 = 4(x - 9); - 4x + y = 45
Dy - 9 = 4(x + 9); - 4x + y = 45

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

details

step-by-step explanation:

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
