document.write( "Question 409457: still not sure of this answer. graph (-2,5) slope of -1 I know the formula is y=mx+b so would that be y=-1x+5 so then -1x+5-1x+5 x= -5 or am i way off?? \n" ); document.write( "

First of all, \"y+=+mx+%2B+b\" is not a formula, it is simply a general equation of a line (in slope-intercept form). Just like the other tutor said, there is no formula involved in this problem.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The slope is -1, so we already know \"m+=+-1\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since (-2, 5) is a point on the line, then we can substitute x = -2, y = 5 into our equation \"y+=+%28-1%29x+%2B+b\" (because if a point lies on the line then equality must occur) to obtain \"5+=+%28-1%29%28-2%29+%2B+b\" --> \"b+=+3\". Hence, the equation of the line is \"y+=+-x+%2B+3\".\r
