Question

Find the equation of the line parallel to 9x + 8y = 13 and passing through (c, d) where c and d are non-zero constants.

I'm not sure how to do this one. I've found the slope of the given equation to be -9/8, so the final equation has to have -9/8x in it for sure. Pretty sure it has to have a +D in it, also.

Answer 1

remember the parrallel lines have same slope.

Answer 2

have you understand

Answer 3

I understand that -9/8 is the slope for both equations. I think I have to add +d at the end of the equation for the parallel line because it has to pass through that y-value. Would I put c in with x? So... the equation would look like this:\[y=-9/8 (x+c)+d\]Does that look about right?

Answer 4

right if answer is this

Answer 5

this is right answer,nice work

Answer 6

Oh okay, thank you. I wasn't sure if I was doing this the right way. I appreciate the help.
