Question

What is the slope of a line parallel to the line with equation 2x – 5y = 9?
A. -9/5
B. -5/2
C. -2/5
D. 2/5

Answer 1

I'm still confused.. :/

Answer 2

oops should be add 5y to both sides of the equation...what do you get..?

Answer 3

Hmm.. I'm still confused, is it A?

Answer 4

ok... I'll attempt to start to make y the subject, this will get the line into slope intercept form.

2x -5y = 9
+5y +5y add 5 y to both sides of the equation
---------------

2x = 9 + 5y
-9 -9 subtract 9 from both sides of the equation
----------------

2x - 9 = 5y

or

5y = 2x - 9

to get the line into slope intercept form divide every term by 5..

then the slope in the number infront of x

Answer 5

Also, parallel lines have equal slopes.

Answer 6

then as @shamil98 said, parallel lines have the same slope. So once you have the slope for your given line, the parallel line has the same slope

Answer 7

Is it D..?

Answer 8

correct... well done

Answer 9

Thanks!
