You can put this solution on YOUR website!

\n" ); document.write( "1. Find the slope of the line that passes through the points (-3, -5) and (3, 2).
\n" ); document.write( "slope= [2--5]/[3--3]=7/6
\n" ); document.write( "-----------------------------------
\n" ); document.write( "2. Find the equation, in slope-intercept form, of the line that passes through the points (-3, 1) and (-2, -5).
\n" ); document.write( "slope = [-5-1]/[-2--3] = [-6]/[1]=-6
\n" ); document.write( "y-1=-6(x--3)
\n" ); document.write( "y=-6x-18+1
\n" ); document.write( "y=-6x-17
\n" ); document.write( "--------------\r
\n" ); document.write( "\n" ); document.write( "3. Find the equation, in standard form, with all integer coefficients, of the line perpendicular to x – 2y = 24 and passing through (1, 3).
\n" ); document.write( "The give line has slope=1/2; The line you want must have slope -2
\n" ); document.write( "y-3=-2(x-1)
\n" ); document.write( "y=-2x+5
\n" ); document.write( "------------------------ \r
\n" ); document.write( "\n" ); document.write( "4. Solve the system of equations using the substitution method.
\n" ); document.write( "If the answer is a unique solution, present it as an ordered pair: (x, y). If not, specify whether the answer is “no solution” or “infinitely many solutions.”
\n" ); document.write( "1st: 7x + y = 1
\n" ); document.write( "2nd: 3x + 2y = -9
\n" ); document.write( "-------------
\n" ); document.write( "Solve 1st for y: y=-7x+1
\n" ); document.write( "Substitute into 2nd to solve for x:
\n" ); document.write( "3x+2(-7x+1) = -9
\n" ); document.write( "3x-14x+2=-9
\n" ); document.write( "-11x=-11
\n" ); document.write( "x=1
\n" ); document.write( "y=-7(1)+1
\n" ); document.write( "y=-6
\n" ); document.write( "Solution: (1,-6)
