stamp · Answer

So if you have a line in the x,y coordinates, its slope is the fraction (ratio) formed by its y change to its x change, rise / run, up / across

but how would i find the slope of

-3x=3y+ 9

stamp · Answer

Thats a line equation. Line equations let you plug in a value (x or y) and receive a point (x, y). Two points make a line is fundamental. Let's find two points.

stamp · Answer

-3x=3y+ 9

x = 0 @ (0, y) ---> -3(0) = 3y + 9 --> 0 = 3y + 9 -> y = -3

Point 1 (0, -3)

x = 1 @ (1, y) ---> -3(1) = 3y + 9 --> -3 = 3y + 9 -> y = -4

Point 2 (1, -4)
