The Answer is: $4.50 for 75 copies. Each copy is .06
Step-by-step explanation:
Equ of line -
y=mx+c
Using point (3,-1)
3 as x, - 1 as y
M=2/3
Substitute the values of these coordinates
3=2/3(-1) +c - - - - now find for c
c= 3- (-2/3)
c= 3.67
Now with the value of c, put the values back into the equation form .. Assuming we don't have a point to work with
y=2/3x + 3.67
Answer:
1. The pin’s location aids to create two drawings simultaneously. This is that while drawing an image, a copy, which may vary in size, is created at the same time.
2. The pantograph relates to dilation and similarity due to the use of similar triangles that affect the scale of the second drawing.
3. The use of similar triangles illustrates the process of the pantograph because the ratio of similitude is set when determining where to place the pin. When a triangle is moved while tracing a line, along with the outline of the image, an enlarged/reduced version of the image is created by the other pantograph's end.
4. The pantograph is now obsolete and has been replaced by several different ways of producing duplicates such as photocopying, mass printing, and digital filing.
When a line is perpendicular to another line with a given slope, you can use the given slope of the original line to find the slope of the perpendicular line. All you need to do is flip the reciprocals. Since the slope of the given line is -1/8x, the slope of the perpendicular line would be 8x. Since there is only one line with a slope of 8x in the answer choices, your answer would be:
a. y=8x+13
