First write the equation of the line in the slope-intercept form:
the slope of this line is m1=-4/7
Second we find the slope of the line perpendicular to the line
We know perpendicular lines have reciprocal negative slopes: m2=-1/m1, therefore
m2=7/4. Now we write the equation of the line through the point (7, 3) and
perpendicular to the line :
, write it in standard form: } =>
.
Done.
