What is the equation of the line with (1,0) and (6,6)?
ch4aika [34]

Answer:

  6x -5y = 6

Step-by-step explanation:

You can use the 2-point form of the equation of a line to find it.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (6-0)/(6-1)(x -1) +0

  y = 6/5(x -1) . . . . . . point-slope form

  y = (6/5)x -6/5 . . . . slope-intercept form

  5y = 6x -6

  6x -5y = 6 . . . . . . . standard form

Find the determinant of the following matrix. A =<br>-2 6<br>3 5​
Blababa [14]

Answer:

|A| = - 28

Step-by-step explanation:

Given

A = \left[\begin{array}{cc}-2&6\\3&5\end{array}\right]

Required

Determine the determinant

For a two by two matrix, A such that:

A = \left[\begin{array}{cc}a&b\\c&d\end{array}\right]

The determinant |A| is:

|A| = a * d - b * c

So, in

A = \left[\begin{array}{cc}-2&6\\3&5\end{array}\right]

The determinant is:

|A| = -2 * 5 - 6 * 3

|A| = -10 - 18

|A| = - 28
