You can print a copy of the graph, stick a pin in the origin, and rotate it 180° to see where the figure ends up.
The origin is the midpoint between each vertex and its image.
Negate every coordinate value, for example,
J(-5, -3) gets rotated to
J'(5, 3).
Answer:
m-5 Tray would be Bill's amount of pencils
3x(2) - 5
6x - 5 is the simplified form
^ means to the power of with nothing after it, it's miss-used. Solving without the ^ symbol it is -2xy with the ^ symbol it's irrational and cannot be solved.
Answer:
Step-by-step explanation:
The equation of the line you will find should be in the form y =mx+c , where m is the gradient and c is the y intercept.
The gradient of a line that is perpendicular to a line [of a known gradient] is the negative reciprocal of the gradient of the first. i.e. if a is the known gradient and the perpendicular gradient is b, ab = -1. Therefore the -3b=-1 and b= 1/3
you can now write y = mx +c as y = 1/3x +c
As you have been given a coordinate, you can input these values into y= 1/3x + c
-12 = 1/3(6) +c
-12 - 2 = c
c = -14
hence the equation of the line is y= 1/3x -14
