Y=3x-4
Because your slope is 3 when you do change in y over change in x. Y intercept is neg 4.

Options: <br> y= -2x - 6<br> y= 2/3x + 6<br> y= -2/3x + 6<br> y=2x + 6

Answer:

y = - $\frac{2}{3}$ x + 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (0, 6) and (x₂, y₂ ) = (6, 2) ← 2 points on the line

m = $\frac{2-6}{6-0}$ = $\frac{-4}{6}$ = - $\frac{2}{3}$

The line crosses the y- axis at (0, 6) ⇒ c = 6

y = - $\frac{2}{3}$ x + 6 ← equation of line

AC = c/3 Bd = 4 - c

Pepsi [2]

The diagonals of a rectangle are congruent
meaning AC and BD are congruent
c/3 = 4-c
multiply both sides by 3
c = 12 -3c
add 3c to both sides
4c = 12
divide both sides by 4
c = 3

So the diagonals are
AB = c/3 = (3)/3 = 1
BD = 4-c = 4- (3) = 1

Hope this helps

Answer:

For h= 25, b in the plane spanned by a1 and a2

Step-by-step explanation:

$a1= \left[\begin{array}{c}1\\2\\-1\end{array}\right] \\a2 = \left[\begin{array}{c}-7\\-7\\2\end{array}\right] \\\\b = \left[\begin{array}{c}3\\-22\\h\end{array}\right]$

we have to find value of h for which b in the plane spanned by a1 and a2.

For this the linear systems given by the following augmented matrix must be consistent.

$\left[\begin{array}{cc|c}1&-7&3\\2&-7&-22\\-1&2&h\end{array}\right]$

Reduce the augmented matrix into row echelon form:

$R_{2} - 2R_{1} , R_{3} + R_{1}\\\\\left[\begin{array}{cc|c}1&-7&3\\0&7&-28\\-0&-5&h+3\end{array}\right]\\\\7R_{3}+5R_{2}\\\\\left[\begin{array}{cc|c}1&-7&3\\0&7&-28\\-0&0&7h-175\end{array}\right]$

For system to be consistent:

$7h-175 =0\\7h=175\\h=25$
