Question

Write an equation of the line containing the given point and parallel to the given line.
(9,-7); 7x-4y=5
the equation of the line is y=?

campbell_st · Answer

for the line 

7x -4y = 5

make y the subject so you can identify the slope of the line...

phi · Answer

add  +4y to both sides as a first step
7x -4y + 4y = 4y+5

can you simplify the left side (of the = sign) ?

anonymous · Answer

ok so how do I do thst then? im so confused

phi · Answer

-4 dollars plus 4 dollars
-4 cows plus 4 cows
or
4 cents - 4 cents
4 y's -  4 y's

you get the same answer for each of those .

anonymous · Answer

okay so how wouls I solve it to find it

anonymous · Answer

equation of any line parallel to 7x-4y=5 is
7x-4y=c
 because it passes through (9,-7)
put in the above eq.and find the value of c
and then finally put the value of c.
