OpenStudy (ivettef365):
just substitute the x on the function for -3
OpenStudy (ivettef365):
so youhave 5(-3) - 9 = ??
OpenStudy (anonymous):
yes ! so that would turn into -15 - 9 , which equals -24 ?
OpenStudy (ivettef365):

what about What is the x-coordinate of the x-intercept of the line that passes through points (-5, 3) and (1, -3)?
