Question:
Answers
y=-1
Step-by-step explanation:
The two lines are parallel,they have the same slope and slope=0
and the y-intercept is -1
so y=0x+(-1) y=-1

The correct option is
(B) [tex]y-(-1)=\dfrac{2}{3}(x-(-6)).[/tex]
Step-by-step explanation: Given that Audrey is trying to find the equation of a line parallel to [tex]y=\dfrac{2}{3}x-5[/tex] in slope-intercept form that passes through the point (-6, -1).
We are to find the equation of the line that she use.
The given line is
[tex]y=\dfrac{2}{3}x-5~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
Comparing the above equation with the slope-intercept form [tex]y=mx+c,[/tex], we have
[tex]\textup{slope, m}=\dfrac{2}{3}.[/tex]
We know that the slopes of two parallel lines are equal.
So, the slope of the new line will also be
[tex]m=\dfrac{2}{3}.[/tex]
Since the line passes through the point (-6, -1), so its equation will be
[tex]y-(-1)=m(x-(-6))\\\\\\\Rightarrow y-(-1)=\dfrac{2}{3}(x-(-6)).[/tex]
Thus, the required equation of the line is
[tex]y-(-1)=\dfrac{2}{3}(x-(-6)).[/tex]
Option (B) is CORRECT.
Given the line with equation [tex]y=\dfrac{2}{3}x-5.[/tex]
Parallel lines have the same slopes, so the parallel line has equation
[tex]y=\dfrac{2}{3}x+a.[/tex]
This line passes through the point (-6,-1), then its coordinates satisfy the equation:
[tex]-1=\dfrac{2}{3}\cdot (-6)+a,\\ \\a=-1+4,\\ \\a=3.[/tex]
Therefore, the equation of needed line is
[tex]y=\dfrac{2}{3}x+3.[/tex]
y = - 9
Step-by-step explanation:
y = - 2 is a horizontal line parallel to the x- axis.
A parallel line must also be horizontal with equation
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (7, - 9) with y- coordinate - 9, thus
y = - 9 ← equation of parallel line
y-(-1)=2/3 (x-(-6)
Step-by-step explanation:
So, we want to write an equation that is parallel to the original, and passes thru (-6,-1)... all that needs to be done is plug it in. Using the unsimplified slope intercept form, y-y1=m(x-x1), you will plug in the X and the Y. It will look like
y-(-1)=m (x-(-6), then since we want it to be parallel, you take the same slope from the other equation, because parallel lines never intersect. So then replace the "m" with "2/3". It should look like y-(-1)=2/3 (x-(-6).
A line parallel to y = 2/3 x - 5 will have a slope of 2/3.
The equation of a line passing through (-6, -1) with a slope of 2/3 is
y - (-1) = 2/3 (x - (-6))
Did u get anything? im also on this question
Parallel lines
the answer is y=2/3(x)+3
