yes
OpenStudy (ashes.boom):
so now you have y = mx + 300
OpenStudy (ashes.boom):
remmebr how to find the slope
OpenStudy (beatboxingfetus):
the slope is 150?
OpenStudy (ashes.boom):
slope is a fraction becuase the formula is y2 - y1 / x2 - x1
so use the y intercept as one point and find another point to use for the second one

hmm??
OpenStudy (anonymous):
actually its x2-x1 / y2 - y1 , am i right ?
OpenStudy (ashes.boom):
the y goes first i think
OpenStudy (ashes.boom):
okay so the y intercept is at point 0, 300
OpenStudy (ashes.boom):
the other point i see is 150, 200

200-300 over 150 - 0
OpenStudy (ashes.boom):
100/150
OpenStudy (ashes.boom):
100/150 = 10/15 = 2/3
OpenStudy (ashes.boom):
the line is going down so its subtraction
-2/3
OpenStudy (ashes.boom):
y = -2/3x + 300
