Question

Which of the following is true about the relationship between the slopes of the lines whose equations are 8x - 9y = 5 and 9x - 8y = 1?

Answer 1

They are equal.
They are reciprocals.
They are opposites.

Answer 2

First change them into Slope-Intercept form.
y = mx + b.
m is slope
b is y-intercept

Then you can compare the slopes! (:

Answer 3

8x - 9y = 5 and 9x - 8y = 1?
for 8x - 9y = 5
8x-5=9y separate y to the other side
y=(8/9 )x -(5/9......... EQ 1)

and for
9x - 8y = 1 separate y to the other side
9x-1=8y
y=(9/8)x - 1/8 ....EQ 2) can you see the difference of the slope on each EQ?

Answer 4

the difference on the slope of EQ 1) and EQ 2)

Answer 5

umm no
