Find the equation for each of the following items below:
\n" ); document.write( "a. A line that passes through (6,2) and has a slope of 2.
\n" ); document.write( "Line equation y = mx + b; find m and b.
\n" ); document.write( "m = 2
\n" ); document.write( "b: 2 = 2*6 + b
\n" ); document.write( "b = -10
\n" ); document.write( "Equation: y = 2x - 10
\n" ); document.write( "--------------------------------------
\n" ); document.write( "b. A line that passes though the points (2,4) and (8,16)
\n" ); document.write( "Line equation y = mx + b; find m and b
\n" ); document.write( "m = [16-4]/[8-2] = 2
\n" ); document.write( "b: 4 = 2*2 + b
\n" ); document.write( "b = 0
\n" ); document.write( "Equation: y = 2x
\n" ); document.write( "=======================
\n" ); document.write( "
\n" ); document.write( "c. A line that passes through (7,3) and has a slope of -1.
\n" ); document.write( "same procudure as above
\n" ); document.write( "-----------------------------
\n" ); document.write( "d. A line that passes through (1, 1) and is perpendicular to the line 3x+4Y=12.
\n" ); document.write( "Find slope of give line: 4y = -3x + 12; y = (-3/4)x + 3
\n" ); document.write( "Its slope is -3/4 so the perpendicular line has m = 4/3
\n" ); document.write( "b: 1= (4/3)*1 + b
\n" ); document.write( "b = -1/3
\n" ); document.write( "Equation: y = (4/3)x - (1/3)
\n" ); document.write( "-----------------------------
\n" ); document.write( "e. A circle with a radius of 9 and a midpoint at (3,3)
\n" ); document.write( "(x-3)^2 + (y-3)^2 = 9^2
\n" ); document.write( "================================
