Answer:

$\large\boxed{y-3=-(x-3)}$

Step-by-step explanation:

The point-slope form of an equation of a line:

$y-y_1=m(x-x_1)$

We have the slope m = -1 and the point (3, 3).

Substitute:

$y-3=-1(x-3)$

Naddik [55]

Answer:

y = -13x - 1

General Formulas and Concepts:

Algebra I

Slope-Intercept Form: y = mx + b

m - slope
b - y-intercept

Step-by-step explanation:

Step 1: Define

Identify variables

Slope m = -13

y-intercept b = -1

Step 2: Find Equation

Substitute in variables [Slope-Intercept Form]: y = -13x + -1
Simplify: y = -13x - 1

Korolek [52]

Answer: 137π

The usual formula for a circle centered at (a,b), with radius r,

(x - a)² + (y - b)² = r²

The area of the circle is πr², so 137π

the admission fee for a charity event is 7 dollars for children and 10 dollars for adults the event was attended by 700 people a

ollegr [7]

Given:
$7/child
$10/adult
Total people = 700
Total money = $6,400

First, make two equations.
Let a = # of adults & Let c = # of children.
Let p = total people

1. a+c = 700
2. 10a+7c = 6,400

Then, rearrange the equation to solve for a variable.
c = 700-a

Substitute (700-a) for c, or the # of children in the second equation.
10a+(700-a) = 6400
9a+700 = 6400
9a+700-700 = 6400-700
9a = 5700
9a/9 = 5700/9
a = 633 $\frac{1}{3}$ = # of adults attended

700-633 $\frac{1}{3}$ = c = 66 $\frac{2}{3}$ = # of children attended
