A. y-b=a(x-0)
B. y+b=a(x-0)
C. y-0=a(x-b)
D. y-0=a(x+b)

PLEASE HELP GIVING 50 POINTS!!!

Answers

Answer 1

Step-by-step explanation:

General line equation: y = mx + c, where m is the slope of the line and c is the y-intercept.

We have y = ax + b.

=> y - b = ax

=> y - b = a(x - 0).

The answer is option A.

Answer 2

Answer:

A

[tex]general \: equation \: of \: line \\ y = mx + c \\ from \: the \: data \: given \\ m = a \\ c = b \\ y = ax + b \\ y - b = ax \\ y - b = a(x - 0)[/tex]

Write equation of a line in point slope form that passes through (3,8) and has a slope of
5?

Answers

Answer:

 y = 5x - 7

Step-by-step explanation:

(3 , 8) ; slope(m) = 5

Equation of the line: y - y₁ = m( x- x₁)

y - 8 = 5(x - 3)

y -8 = 5x - 5*3

y-8 = 5x - 15

   y = 5x - 15 +8

  y = 5x - 7

Answer:

50.2 cm^2

Step-by-step explanation:

Formula for the area of a circle: [tex]\pi r^{2}[/tex]

Radius of bigger circle = 5

Area of big circle = 25 * 3.14 = 78.5

Radius of smaller circle = 3

Area of small circle = 9 * 3.14 = 28.26

Now, we subtract:

78.5 - 28.26 = 50.24 <--- Because we have to round to the nearest tenth, the final answer is 50.2
