Answer:

Zer0

Step-by-step explanation:

If a linear line is parallel to the x-axis, in other words, it is horizontal, the slope has to be 0.

There is no steepness to the line, and steepness is essentially what slope is.

Hope this helps!!

Find the equation for the line of best fit using the two points that are close to the line of best fit (2,70) and (4.5, 90)

kari74 [83]

Given:

Two points that are close to the line of best fit are (2,70) and (4.5, 90).

To find:

Th equation of best fit line using the given two points.

Solution:

We know that, if a line passes through the two points, then the equation of line is

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)$

Two points (2,70) and (4.5, 90) are close to the best fit line.

Consider the two points (2,70) and (4.5, 90). So, the equation of line is

$y-70=\dfrac{90-70}{4.5-2}(x-2)$

$y-70=\dfrac{20}{2.5}(x-2)$

$y-70=8(x-2)$

$y-70=8x-16$

Adding 70 on both sides, we get

$y=8x-16+70$

$y=8x+54$

Therefore, the equation of best fit line is $y=8x+54$ .

Gavin was thinking of a number gavin divides by 5 then adds 8 to get the answer of 4 what is the original number

Annette [7]

Answer:

Step-by-step explanation:

Method

Let the number be x

x/5 + 8 = 4 Subtract 8

x/5 + 8-8 = 4 -8 Combine

x/5 = - 4 Multiply by 5

x = -4*5

Answer

x = - 20

Check

- 20 / 5 = - 4

- 4 + 8 = 4

Write and simplify the equation you would use to solve the problem below.

charle [14.2K]

Answer:

4w + 10 = 116

Step-by-step explanation:

Call the width w.

The length is 5 more than that, so the length is w + 5

Perimeter is 2w + 2l

2w + 2(w+5) = 116

Distribute the 2 to the values in the parentheses.

2w + 2w + 10 = 116

Combine like terms

4w + 10 = 116
