The slope for both the line is m= 1/3 and they are parallel lines , Option B and C are correct two options
The first equation is
y = (1/3)x-4 and not y = -x-4
(if the equation is not corrected then it will not have two true statements)
<h3>What is a System of Equation ?</h3>
A system of equation is a set of equation which have a common solution
The given system of equation is
y = (1/3)x-4
3y -x = -7
3y = x-7
As it can seen from the standard equation of a line that
y =mx+c
so slope for both the line is m= 1/3
Therefore they are parallel lines
Thus , Option B and C are correct two options

Answer:
y = -2x - 6
Step-by-step explanation:
We know that the slopes of the lines are equal when the lines are parallel to each other.
So, the equation of the given line is<u> y = -2x + 2.</u>
Here,
y = mx + c
y = -2x + 2
slope ⇒ m ⇒ -2
Therefore, the slope of the new line will be ( - 2 ).
<u>And now we have to find the y-intercept ( c ).</u>
For that let us use the given coordinate.
( -6 , 6 ) ⇒ ( x , y )
To find the y-intercept we have to make c the subject of the equation y mx + c.
Also, we have to replace m with ( - 2 ) as the slope of the new line is -2.
<u>Let us solve it now.</u>
y = m x + c
6 = -2 × -6 + c
6 = 12 + c
6 - 12 = c
-6 = c
Now we have found that,
m ⇒ - 2
c ⇒ -6
<u>And now let us write the equation of the line.</u>
y = m x + c
<u>y = -2x - 6</u>
The answer is 68°
step by step :
DENSITY =MASS/VOLUME
OR MASS = DENSITY X VOLUME
DENSITY =1.5 g/ml AND VOLUME = 10 ml
MASS = 1.5 x 10 = 15 g
Answer:
for the fractions or decimals part, round it up then make your equation, just multiply properly, what I do is, if I have a question like 23x17, I do 23x7, then 23x1, then add it,
