what is the slope and y intercept of −5x = 8−y

Answers

Answer:

im pretty sure its -5

Step-by-step explanation:

The slope-intercept form is  y = m x + b

where  m

is the slope and  b

is the y-intercept.

y = m x + b

Using the slope-intercept form, the slope is  

− 5 . m = − 5                                                                                                                        i think im right but if this helpful  your welcome uwu                    

Answer:

Slope is 5 and y-intercept is 8

Step-by-step explanation:

-5x = 8 - y                   Solve for y

-5x - 8 = -y                

  5x + 8 =  y                 multiply by -1

  So y = 5x + 8

   Using y = mx + b      "m"     is the slope 5     "b" is the y-intercept

Use the point and the slope to graph each line. Write the equation of the line.
The line passes through point (4,0) and has slope 0.5.

Answers

Answer:

slope = 0.5=1/2

using the formula y-y1 = m (x -x1)

y - 0 =1/2(x - 4)

y = 1/2 (x -4); cross multiply

2y = x -4

divide both sides by 2

y = 1/2x -2

y = 0.5x -2(equation of the line)

Which statement compares the two numbers correctly?

Answers

Answer:

64.48 (I am 45% sure) The number are mixed and hard to understanding.  

Step-by-step explanation:

The linear equation of the total amount paid in the first 12 months will be y = 64.48x - 2.48.

What is the linear system?

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

Modern Electronics offers a one-year monthly installment plan for a big-screen TV.

The payment for the first month is $62, and then it increases by 4% each month for the rest of the year.

Then the payment after a month will be

Monthly payment = 1.04 × 62

Monthly payment = $64.48

Then the linear equation of  the total amount paid in the first 12 months will be

y = 64.48(x - 1) + 62

Where y is the cost and x is the number of months.

The equation can be written as

y = 64.48x - 2.48

Answers

Answer:

I think it's 8 and 12

Answer:

12 and 8

Step-by-step explanation:

We can find the mean by adding all of the numbers and then dividing the total by the ammount of numbers we added. In this case we are adding 12 and 8. This gives us 20. We then divide 20 by 2 and get our mean which is 10. The range is the ammount that needs to be subtracted from the highest number to the lowest number. In this case 12 subtracted by 4 gives us 8 while still allowing for there to be a mean 10.
