what's the equation for points (0,-5) (-3,-2)?
----------------------------
Points don't have equations, lines and planes have equation.
Since there are only 2 points, the only type of line that can be defined by them is a straight line, which has a linear equation.
---------------
To find the equation of the straight line passing thru these 2 points, first find the slope, m, of the line.
n = diffy/diffx = (-2-5)/(-3-0)
m = 7/3
-------
Then use either point in
y-y1 = m*(x-x1)
y+5 = (7/3)x
y = (7/3)x - 5 (slope-intercept form)
7x - 3y = 15 (standard form)

Slope, or m = = = = - 1

Using the point-slope formula, we have:
----->
------> --- Slope-intercept form, or,
---- Standard form
