At 109°F, a certain insect chirps at a rate of 98 times per minute, and at 112°F, they chirp 122 times per minute.
\n" ); document.write( " Write an equation in slope-intercept form that represents the situation.
\n" ); document.write( ":
\n" ); document.write( "Assign the given values as follows
\n" ); document.write( "x1=109; y1=98
\n" ); document.write( "x2=112; y2=122
\n" ); document.write( "Slope formula m = $\"%28%28y2-y1%29%29%2F%28%28x2-x1%29%29\"$
\n" ); document.write( "m = $\"%28%28122-98%29%29%2F%28%28112-109%29%29\"$ = $\"24%2F3\"$ = 8 is the slope
\n" ); document.write( ":
\n" ); document.write( "Find the equation using the point/slope form y - y1 = m(x - x1)
\n" ); document.write( "y - 98 = 8(x - 109)
\n" ); document.write( "y - 98 = 8x - 872
\n" ); document.write( "y = 8x - 872 + 98
\n" ); document.write( "y = 8x - 774 is the equation
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "you can check this for yourself, see if the given values for x yield the value for y \n" ); document.write( "

\n" );
