Question 97572: Write the equation of the line in slope intercept form that passes through point (3, –18) with a slope of –7. i have been trying this for about an hour and can not seem to find the answer or at least how to right it Answer by checkley71(8403) (Show Source):
You can put this solution on YOUR website! Y=mXb WHERE (m)=SLOPE & (b)=Y INTERCEPT.
NOW SUBSTITUTE THE SLOPE (-7) FOR (m) & THE X & Y VALUES & SOLVE FOR b
-18=-7*3+b
b=-18+21
b=3 FOR THE Y INTERCEPT;
THUS THE LINE EQUATION IS
Y=-7X+3
