Equation in point-slope form is:y+1=9(x+8)

Step-by-step explanation:

We are given slope m= 9 and point (-8,-1) and we need to find an equation in point-slope form for the line.

The standard equation of point-slope form is:

y-y_{1}=m(x-x_{1})

So putting value of slope m= 9 and x₁= -8 and y₁= -1 the equation in point-slope form is:

y-y_{1}=m(x-x_{1})\\y-(-1)=9(x-(-8))\\y+1=9(x+8)

So, equation in point-slope form is:y+1=9(x+8)

What is the value of x?<br><br><br><br> Enter your answer in the box.
Tamiku [17]

It's a hexagon.

The formula of the sum of internal angles in the polygon:

S=(n-2)\cdot180^o

Therefore

112^o+133^o+128^o+100^o+120^o+x^o=(6-2)\cdot180^o\\\\593^o+x^o=720^o\ \ \ \ |-593^o\\\\x^o=127^o

Points and their residual values are shown in the table. a 3-column table with 5 rows. the first column is labeled x with entrie
maksim [4K]

The residual value, which is the farthest from the line of best fit for the table which shows points and their residual values, is 0.7.

<h3>What is residual value?</h3>

The residual value is the estimated value which is calculated for the end of the lease terms for a fixed asset.

Points and their residual values are shown in the table. A 3-column table with 5 rows.

  •  x                               1,     2,     3,     4,     5.
  •  y                               2,   3.5,   5,    6.1,    8.
  • Residual Value       -0.4, 0.7,  -0.2, -0.6   0

The simple regression line can be represented as,

\hat y=\alpha +\beta X+\hat e

Here α is the constant, β is the slope and <em>e </em>is the residue.

The point which is farthest from the best fit of the line is 3.5. At y=3.5, the value of residue is 0.7.

Thus, the residual value, which is the farthest from the line of best fit for the table which shows points and their residual values, is 0.7.
