Answer:

y-2=2/3(x+1) OR y=2/3x+8/3

Step-by-step explanation:

y=2/3x-2 (2/3 represents your slope)

plug into this equation y-y1=m(x-x1) (m represents your slope, y1 and x1 are you points)

so y-2=2/3(x+1) OR y=2/3x+8/3 (move the -2 over, distribute the 2/3 to (x+1) and then add 2/3 to the 2 you moved over)

Area

$\\ \tt\longmapsto \dfrac{1}{2}|x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)|$

$\\ \tt\longmapsto \dfrac{1}{2}|(-2)(3+5)+(4)(-5-1)+(-2)(1-3)|$

$\\ \tt\longmapsto \dfrac{1}{2}|-16-24+4|$

$\\ \tt\longmapsto \dfrac{1}{2}|-36|$

$\\ \tt\longmapsto 18units^2$

(x-4)*(x-9)=0 what is x

Strike441 [17]

Answer:

x either equals to 4 of 9 so you can write it like x=4, 9

Step-by-step explanation:

Start by simplifying each sides of the equation.

x^2-13x+36=0

Then factor the left side of the equation.

(x-4)(x-9)=0

Set factors equal to 0

x-4=0 or x-9=0

x=4 or x=9
