<u>Angle measures:</u>

a = x = z = 51° (as vertical angles and corresponding angles)
b = d = y = w = 180° - 51° = 129° (as supplementary angles and corresponding angles)

Supplementary angles for a linear pair and sum to 180°.

<u>Examples are:</u>

a and b or

2<br> v<br> What is the equation of a line that is parallel to y = -4x – 3 and shifted down 3 units?

Ugo [173]

Answer: $y=-4x-6$

Step-by-step explanation:

Given

The equation of line is $y=-4x-3$

The line which is parallel to the given line is $y=-4x+c$

and shifted by 3 units down i.e. its y-intercept is 3 units below the given line

$\therefore y=-4x-3-3\\\Rightarrow y=-4x-6$

jarptica [38.1K]

First, you set up the equation which would be 5y-8=3y-4.
-3y -3y
2y-8= -4
+8 +8
2y=4
divide by 2
y=2

Y = 2x <br> x + y = −6<br> the answer should be like this (x,y) or ( , )

melisa1 [442]

Answer:

(-2, -4)

Step-by-step explanation:

Given:

The system of equations to solve is given as:

$y=2x\\\\x+y=-6$

In order to solve this system of linear equations, we use substitution method.

In substitution method, we substitute the value of any one variable in the other equation.

So, we substitute the value of 'y' from first equation in the second equation.

This gives,

$x+2x=-6\\\\3x=-6$

Dividing both sides by 3, we get:

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

Now, $y=2x=2\times -2=-4$

Therefore, the solution is (-2, -4)
