Pls help me on this PLS
Write an equation of the line that is parallel to the graph of y-3x=4 and has the same y-intercept as the graph of 4y+x=36.

anonymous · Answer

when you say parallel, therefor, their slope are the same. .

(1) find the y intercept of the second equation
         4y=-x+36
           y= -1/4 x +9   y-intercept is 9

(2) find the slope of the first equation
      y=3x+4      m(slope)=3

therefor the, using the slope=3 and the point (0,b) which is (0,9) ,since the y-intercept is 9, therefor the equation parallel to the first equation and the same y-intercept of the second equation is

      y=3x +9
