Answers

Answer:

Step-by-step explanation:

If product of mean = product of extreme, then ratios are equivalent.

18 : 12 :: 16:20

Product of mean = 12 * 16 = 192

Product of extreme = 18 * 20 = 360

Graph the equation x-y=6

Answers

$x-y=6\n\nThe\ slope-intercept\ form:y=mx+b\n\n-y=-x+6\ny=x-6\n\ny-intercept\ (x=0)\ny=0-6=-6\n(0;-6)\n\nx-intercept\ (y=0)\n-x+6=0\nx=6\n(6;\ 0)$

x-y-6=0 is the standard form you can graph this by using the y-x intercept form
x-intercept y=0
x-6=0
x=6
y-intercept, x=0
-y-6=0
-y=6
y=-6
therefore you can plot points on (0,-6) and (6,0) ad connect them together
