document.write( "Question 100247: I need to find the intercepts, graph and check for symmetry. y=-5x, could someone show me this one also step by step? I tried to do it and came up with 1,-5, on the symmetry I'm not sure if my answers amake sense. For example I have y=5x for the x-axis, does that make it symmetric? \n" ); document.write( "

Ok first when asked to find the intercepts of a line, what is being asked is where does the line cross the x axis and where does the line cross the y axis.
\n" ); document.write( "To find the x intercept you must plug in zero for y in your equation
\n" ); document.write( "So
\n" ); document.write( "y=-5x
\n" ); document.write( "replace y with zero
\n" ); document.write( "0=-5x
\n" ); document.write( "divide both sides by -5
\n" ); document.write( "0=x
\n" ); document.write( "This shows us that the line y=-5x will cross the x axis at zero
\n" ); document.write( "Now lets see where the line crosses the y axis
\n" ); document.write( "To find the y intercept you must plug in zero for the x in your equation
\n" ); document.write( "y=-5x
\n" ); document.write( "replace x with zero
\n" ); document.write( "y=-5(0)
\n" ); document.write( "multiply -5 and zero
\n" ); document.write( "y=0
\n" ); document.write( "This shows that the line y=-5x will cross the y axis at zero too
\n" ); document.write( "Here is a a graph of the line showing that it crosses both x and y axis at zero
\n" ); document.write( " $\"+graph%28+300%2C+300%2C+-5%2C+5%2C+-5%2C+5%2C+-5x%29+\"$ \n" ); document.write( "
