what is the standard form of equation line passing through (5,-3) with a slope of -3

Question

Ok, y = 3x + C -- line with slop of 3. Let's find C: -3 = 3*5 + C => C = -18. And the standard form is y = 3x - 18.

A linear equation is written in general terms     y = mx + c
Where m is the gradient of the line or its slope and c is the point of intercetion on the y axis.
Given the coordinate pair and the slope substitute for m, x and y and start to build the equation.
 
y = mx + c  becomes...
-3 = (-3)(5) + c 

therefore...
-3 = -15 + c   adding 15 to both sides...
12 = c

And so the equation for this line is...
y = 12 -3x

Nikita I think you forgot the negative in the value of m.
