Question

write the slopeintercept equation for the line that passes through(-7,6) and is perpindicular to -7x+9y=-2 plz help

Answer 1

Can you find the slope of -7x+9y=-2 ?

Answer 2

i do not understand this at all

Answer 3

Do you want to know how to solve the problem, or do you just want the answer?

Answer 4

i wana know how to do the problem but i need the answer im on a time crunch

Answer 5

Will you continue to work on how to do it after I give you the answer?

Answer 6

well we can wk it now cause i have to know how to do it,if i cant get right can u help with answer

Answer 7

Sure!
First, do you know how to change the equation to the slope-intercept form?

Answer 8

i know nothing at all

Answer 9

when i read about it i dont comprehend it

Answer 10

Do you take math classes, or are you home schooled?

Answer 11

im in classes in college with 4.0 but this math is killing it...worst subject :(

Answer 12

Looks like you need to put more time on this math thing.
The equation represents a line in a graph, is that OK?

Answer 13

k

Answer 14

Like this:

Answer 15

its my only class at moment an im all into it i study alot just not grasping it

Answer 16

That's OK, we have to start somewhere!
The equation can be put into different forms, for example:
-7x+9y=-2
If we add 7x to both sides, the equation becomes
9y=7x-2
Now if we divide by 9 on both sides, it becomes
y=(7/9)x - (2/9)
Is that ok so far?

Answer 17

yes just lookin it over

Answer 18

The equation has now been transformed into the "slope-intercept" form, which has y on the left, and two terms on the right (with x and without x).

Answer 19

ok so far so good

Answer 20

Great!
The number to which "x" is multiplied (7/9) is called the slope of the line. We usually represent this number by the letter m.
The bigger this number, the steeper the line.
A 45 degree line has a slope of 1, and a slope of 100 is almost vertical, and a slope of 0 is horizontal.
