\n" ); document.write( "(-5,-5) , (10,-2)
\n" ); document.write( ".
\n" ); document.write( "Find the slope:
\n" ); document.write( "m=change in y/change in x=(-5-(-2))/(-5-10)=-3/-15=1/5
\n" ); document.write( ".
\n" ); document.write( "Slope intercept form:
\n" ); document.write( "y=mx+b
\n" ); document.write( "We have m=1/5:
\n" ); document.write( "y=(1/5)x+b
\n" ); document.write( "Put in values from one point and solve for b:
\n" ); document.write( "Using point (-5,-5):
\n" ); document.write( "-5=(1/5)(-5)+b
\n" ); document.write( "-5=-1+b
\n" ); document.write( "-4=b
\n" ); document.write( "Using values for m and b:
\n" ); document.write( "y=(1/5)x-4 ANSWER: This is the equation in slope-intercept form.
\n" ); document.write( ".
\n" ); document.write( "CHECK:
\n" ); document.write( "Use the other given point (10,-2):
\n" ); document.write( "y=(1/5)x-4
\n" ); document.write( "-2=(1/5)10-4
\n" ); document.write( "-2=2-4
\n" ); document.write( "-2=-2 \n" ); document.write( "
