Find the equation of the line that is parallel to y=-3x+1 and passes through (9,0)

(1) Answers

simple, y=mx+c is general form of strainght line m is the slope. for 2 lines to be parallel , they must have same slope . in this case , m=3 any line parallel to given line can be given by y= 3x+c where different values of c give different parallel lines . now for this line to pass through (9,0) , the point should satisfy the equation of line. so substitute..... 0=3*9+c you get c= -27 so the answer is y=3x-27
