Answer:

Step-by-step explanation:
The point-slope form of an equation of a line:

<em>m</em><em> - slope</em>
<em>(x₁, y₁)</em><em> - point on a line</em>
<em />
We have

Substitute:

-2y-4=4(y-1)
Always remove the pararentheses as your first step.
-2y-4 = 4y - 4
Combine like terms.
-2y - 4y = 4 - 4
-6y = 0
Divide both sides by -6 to find y.
-6y/-6 = 0/-6
y = 0
Done
Answer:
Step-by-step explanation:
Just divide y by x and what ever you get is the answer
Hope this helps!
Answer:
a. 8x + 4y = −4
17x + 2y = −28
Step-by-step explanation:
{6x + 2y = −6
{3x − 4y = −18
{6x + 2y = −6
{1½x - 2y = −9
___________
[Plug this back into both equations above to get the y-coordinate of 3]; 
Alternatively, you plug the solution of
into the top answer choice to get this:
{−16 + 12 = −4 ☑
{−34 + 6 = −28 ☑
These are genuine statements, therefore this system of equations is the system we are looking for.
