Write an equation of the line passing through the points (4.15) and (-1. - 15).

jolli1 [7]

Answer:

y = 6x - 9

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

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

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step-by-step explanation:

Step 1: Define

Point (4, 15)

Point (-1, -15)

Step 2: Find slope m

Substitute: $m=\frac{-15-15}{-1-4}$
Subtract: $m=\frac{-30}{-5}$
Divide: $m=6$

Step 3: Find y-intercept b

Define: y = 6x + b
Substitute: -15 = 6(-1) + b
Multiply: -15 = -6 + b
Isolate b: -9 = b
Rewrite: b = -9

Step 4: Write linear equation

Substitute in all variables.

y = 6x - 9

And we have our answer!

Here are The ingredients For makeing fish pie for 6 people.180g flour 240 g fish 80g butter 4 eggs 180 ml milk.

GenaCL600 [577]

The amount of ingredients are needed:

For 2 people: Flour = 60 g, Fish = 80 g, Butter = 26 $\frac{2}{3}$ g, Eggs = 2 eggs, Milk = 60 ml

For 15 people:Flour = 450 g, Fish = 600 g, Butter = 200 g, Eggs = 10 eggs, Milk = 450 ml

Step-by-step explanation:

Given,

For 6 people following things are needed:

Flour = 180 g

Fish = 240 g

Butter = 80 g

Eggs = 4

Milk = 180 ml

To find the amount of ingredients for a) 2 people b) 15 people

Now,

a) For 2 people

Since the number of people decreased by $\frac{1}{3}$ rd times

The amount of ingredients will be decreased by $\frac{1}{3}$ times

So, following this are needed:

Flour = 180× $\frac{1}{3}$ = 60 g

Fish = 240× $\frac{1}{3}$ = 80 g

Butter = 80× $\frac{1}{3}$ = 26 $\frac{2}{3}$ g

Eggs = 4× $\frac{1}{3}$ = 1 $\frac{1}{3}$ = 2 eggs

Milk = 180× $\frac{1}{3}$ = 60 ml

b) For 15 people

Since the number of people increased by $\frac{5}{2}$ th times

The amount of ingredients will be decreased by $\frac{5}{2}$ th times

So, following this are needed:

Flour = 180× $\frac{5}{2}$ = 450 g

Fish = 240× $\frac{5}{2}$ = 600 g

Butter = 80× $\frac{5}{2}$ = 200 g

Eggs = 4× $\frac{5}{2}$ = 10 eggs

Milk = 180× $\frac{5}{2}$ = 450 ml
