1st problem : find the equation of the straight line having slope $m$ passing through the point $(a, 0)$. What are the coordinates of the point of intersection of this line with the y-axis?
2nd problem : find an equation of the line passing through the point $(1, 5)$ with a negative slope and forms with the coordinates axis a triangle with area $10$ sq. units. Please I want answers with steps.
Thank you!
