<h2><em><u>YOUR QUESTION WASN'T CLEAR SO I GUESS THIS IS YOUR ANSWER IDF NOT SORRY </u></em></h2>
<u><em>Answer:</em></u>
<em>You haven't attached a picture but this is what your line should look like </em>
<em> </em>
<em>Step-by-step explanation: </em>
<em> </em>
<em>For this equation you simply have to graph it. </em>
<em> </em>
<em>First, you have to remember that these equations follow a formula: y=mx+b. m is the slope of you line and b is the y-intercept. </em>
<em> </em>
<em>Next, you need to graph it. First, graph your b, in this case 2. You would go up 2 on you graph (graph (0,2)). Then, you would graph your slope which is 3. </em>
<em> </em>
<em>Now, remember that slope equals y/x, so think of the number 3 being like 3/1. You would start at (0,2) and go up 3 points in the graph, then over 1 point (graph where you end up). You repeat that from each new point you make until you have enough points to create a straight line. </em>

Answer:
Length of scale = 15 cm
Width of scale = 5 cm
Step-by-step explanation:
Dimensions of the kitchen of Mai are given as:
Length of kitchen = 6 m
Width of kitchen = 2 m
Scale to be used = 1 to 40
To find:
The drawing with labeling and dimensions of the scale drawing.
Solution:
First of all, let us understand about the concept of scaling.
Scaling is a method to represent big structures on paper.
For this purpose, we decide a scaling factor and draw the big structures on paper by scaling down (making it small) by using a scaling factor.
Here, the scale factor used is 1 to 40.
i.e. 1 unit on scale is equivalent to 40 units on the actual kitchen.
40 units of kitchen = 1 unit of scale
1 unit of kitchen = units of scale
6 m of kitchen =
Length of scale = <em>15 cm</em>
40 units of kitchen = 1 unit of scale
1 unit of kitchen = units of scale
2 m of kitchen =
Width of scale = <em>5 cm</em>

Please refer to the attached image as well for representation of given scale.
Answer:
The x co-ordinate o intersection of line k and n is
Step-by-step explanation:
Given as :
The equation of line m is 6 x - 3 y = 7
So, in the standard form , line equation is
y = a x + c , where a is the slope
So, 6 x - 3 y = 7 can be written as
3 y = 6 x - 7
or, y = 2 x - ........1
So, slope of this line = a = 2
Now, The line n is perpendicular to line m and passing through line ( 6 , 2 )
So, Slope of line n = b
For , perpendicular lines , products of slope = - 1
Or, a × b = -1
∴ b = -
I.e b = -
So,equation of line n with slope b and passing through line ( 6 , 2 ) is
y - = b ( x -
)
or, y - 2 = - ( x - 6 )
or, 2 × ( y - 2 ) = - 1 ( x - 6 )
or, 2 y - 4 = - x + 6
or, x + 2 y -10 = 0 ........2
Again, equation of line k with slope 5 and y intercept = 1
For y intercept , x coordinate = 0
y = c x + c
or, 1 = c× ( 0 ) + c
Or, c = 1
Or, equation of line k is
y = 5 x + 1 ..........3
Now intersection of line k and n is
put the value of y from eq 3 into eq 2
I.e x + 2 × ( 5 x + 1 )-10 = 0
Or, x + 10 x + 2 - 10 = 0
or, 11 x - 8 = 0
or 11 x = 8
∴ x =
Hence The x co-ordinate o intersection of line k and n is Answer
