(7z + 5) + (2z - 1) + (6z + 3) + (3z - 9) =

= 7z + 5 + 2z - 1 + 6z + 3 + 3z - 9 =

= 7z + 2z + 6z + 3z + 5 - 1 + 3 - 9 = 18z - 2

RideAnS [48]

Answer:

y=3x-21

a line is parallel if the slopes of the lines are the same

so that means that out line should look something like this

y=3x+b

then, we use our point given to find b

-3=18+b

b=-21

the equation of out line is y=3x-21

How do i solve this?

shusha [124]

Answer:

Step-by-step explanation:

You can use Pythagoras Theorem,

$8^{2} + y^{2} = (8\sqrt{6} )^{2} \\ y^{2} = (8\sqrt{6} )^{2} - 8^{2} \\y^{2} = 384 - 64\\y^{2} = 320\\y = \sqrt{320}$

∴ $y = 8\sqrt{5}$
