Question

Determine the equation of the line with slope -3 and containing (-7,2)

Answer 1

to find the equation of a line
you need 2 points

I am going to make an example

first of all
you have a coordinate
EXAMPLE COORDINATE
(0 , 0)
give it a slope
m = 1
i will just choose any random point



you get your 2 points then you carry on from there

point slope form

y - y1 = m ( x - x1 )
