Answer:

The equation (in y=mx+b form) would be y= -2x+6

Step-by-step explanation:

The slope is given from the start, which is -2, so you would plug that in for m to make the equation y=-2x but this IS NOT YOUR ANSWER

I was able to graph it, although there are multiple ways to do this.

Next you have to find the y-intercept. You use your coordinate (1,4) and go up twice (positive) (1,6) and go to the left (negative) to get the point (0,6) giving you your intercept.

Plugging it into the equation for b, your equation would now be y= -2x + 6 giving you your final answer

Answer:

y = -2x + 6

Step-by-step explanation:

Since we already have the slope we just need to find the y-intercept.

To do that just plug in the point you were given. (1,4)

4 = -2(1) + b (b represents the y-intercept)

4 = -2 + b (add 2 on both sides)

6 = b

y = -2x + 6 is the equation

Hope this helps!!

Susannah has a high-yield savings account into which she deposits $140 each month. At the beginning of the year, Susannah's acco

motikmotik

Answer:

Her account balance will be $2,080 at the end of the year

Step-by-step explanation:

Let

y ----> Susannah's account balance

x ---> is the amount of time in months

we have

$y=140x+400$

This is a linear equation in slope intercept form

where

The slope or unit rate is equal to

$m=\$140\ per\ month$

The y-intercept or initial value is equal to

$b=\$400$

Remember that

One year is equal to 12 months

For x=12 months

substitute in the linear equation

$y=140(12)+400=\$2,080$

What is the inverse of y=3x+3?

larisa86 [58]

Answer:

The inverse is x/3 -1

Step-by-step explanation:

y = 3x+3

To find the inverse, exchange x and y

x = 3y+3

Solve for y

x-3 =3y+3-3

x-3 = 3y

Divide by 3

x/3 - 3/3 = 3y/3

x/3 -1 = y

The inverse is x/3 -1

8 home theaters are sold for each $ 500 spent on advertising

Advertising ($) 1,000 - $ 2,000 - $ 3,000

Home Theaters 16 - 32 - 48

16 home theaters are sold when the amount on advertising is $ 1,000

32 home theaters are sold when the amount on advertising is $ 2,000

48 home theaters are sold when the amount on advertising is $ 3,000

X would = The number of home theaters that are sold when the amout of advertising is $500

16/1,000 = x/500

1,000x = 500 *16

1,000x = 8,000

x = 8,000/1,000

X=8
