give an equation of a line that is perpendicular to the line
\n" ); document.write( "y=1/3x+1
\n" ); document.write( "I have y=-3x+2 or y=-3x-1
\n" ); document.write( "Correct
\n" ); document.write( "-----------------------
\n" ); document.write( "find a point slope form of the line passing through (1980,5) and (2000,45)
\n" ); document.write( "i have y=2x+5
\n" ); document.write( "Correct
\n" ); document.write( "-----------------------
\n" ); document.write( "I'm really confused about that one!
\n" ); document.write( "find an equation of the line that horizontal, passing through (3/4,-5/6)
\n" ); document.write( "y=-5/6, right?
\n" ); document.write( "Correct
\n" ); document.write( "--------------------
\n" ); document.write( "I don't understand this one at all:
\n" ); document.write( "the number of radio stations on the air from 1950 to 1995 may be modeled by
\n" ); document.write( "f(x)=214.3x-415,368, where x is the year
\n" ); document.write( "how many radio stations were on air in 1980
\n" ); document.write( "what is the slope of the graph
\n" ); document.write( "-
\n" ); document.write( "Your equation is messed up; but it looks like the slope is 214.3
\n" ); document.write( "--------------------
\n" ); document.write( "interpret the slope as a rate
\n" ); document.write( "The # of radio stations increases at a rate of 214.3 per year.
