Question 602234: write an equation of the line containing the given points and parallel to the given line. (7,2); 7x-9y=4
Answer by lawdej(58)   (Show Source):
You can put this solution on YOUR website! first find the slope of7x-9y=4
rearrange in the form of y=mx+b ,m=slope
9y=7x-4
y=7/9x-4/9
slope=m=7/9
thus y-y1=slope(x-x1) is the formula to find equation of a line containing a point (x1,y1) and have a slope m
here (x1,y1)=(7,2)
and slope=7/9
y-2=7/9(x-7)
9y-18=7x-49
9y=7x-49+18
9y=7x-31
there for 9y=7x-31 is the required equation line
