(_1_) Use formula for slope to find the slope of both these lines.

(_2_) Use either the point-slope formula OR the slope-intercept formula; AND the given point to form the desired line containing the given point and using the slope found.




-----------------Some useful information-------------------

Slope,

Slope intercept form is y=mx+b, and you can solve this for b:
b=y-mx,
and use the given point to be contained in the line to compute b, which is the y-intercept.
