Question

Using your own words, describe how you would write the equation of a line given a point on the line and a parallel line?

Answer 1

you are given a parallel line this means both lines have the same gradient
the equation for a line is
y=mx+c

so m is the gradient
m is the same for both lines
you are given coordinates
now to work out the equation of the line you do

where y1 is the y coordinate
and x1 is the x coordinate
m is the gradient
sub in
simplify
you are done :D
