The x-intercept of a line is –5 and the y-intercept of the line is –2. What is the equation of the line?
\n" ); document.write( ":
\n" ); document.write( "Using the slope intercept form y = mx + b
\n" ); document.write( ":
\n" ); document.write( "y intercept (-2) occurs when x = 0, therefore we have:
\n" ); document.write( "y = m(0) - 2
\n" ); document.write( ":
\n" ); document.write( "x intercept (-5) occurs when y = 0, therefore, we can find the slope, m
\n" ); document.write( "-5m - 2 = 0
\n" ); document.write( "-5m = 2
\n" ); document.write( " m = $\"2%2F%28-5%29\"$
\n" ); document.write( " m = -.4
\n" ); document.write( ":
\n" ); document.write( "The equation: y = -.4x - 2
\n" ); document.write( "looks like this:
\n" ); document.write( " $\"+graph%28+300%2C+300%2C+-6%2C+5%2C+-6%2C+6%2C+-.4x-2%29+\"$
