Question

Help with this coordinate Geometry problem
In the standard (x,y) coordinate plane, if the x-coordinate of each point is 9 more than 3 times the y-coordinate, the slope of the line is?

Answer 1

hint:

x = 3y + 9

know where to go from here?

Answer 2

Plug in values!

Answer 3

uhhh not quite

Answer 4

start by dividing both sides by 3

Answer 5

I see

Answer 6

i got it!

Answer 7

You need to solve for y to put the equation in the slope-intercept form. Then you can read the slope directly from the equation.

Answer 8

y = mx + b is the slope-intercept form, where m = slope and b = y-intercept.

Answer 9

Ok, the answer is 1/3! Thanks!

Answer 10

Correct.
