Question 1129804


For the first line passing through the origin:

y - 0 = (7/4)(x - 0)  —>  y = (7/4)x  <br>

The slope of the perpendicular line will therefore be  -4/7, so that line has the equation:

y - 7 = (-4/7)(x - 4)<br>

Or in slope-intercept form:
{{{ highlight( y = (-4/7)x  + (65/7) ) }}}
