The length of the football field is 58 yards more than its width. what is the area of the field?
you get 15
then subtract 9 from 180.
180 minus 9 is 171
divide by 15
you get 11.4
slope = -
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x + 7 is in this form with slope m = 2
this line is perpendicular to the side it bisects.
given a line with slope m then the slope of a line perpendicular to it is
= - = -
