the x-intercept is => point (,)
the y-intercept is => point (,)
the equation of the line:

where is a slope and is y-intercept
find a slope using two points above

your equation is:

You can also use the intercept formula for a line which is:



where 'a' is the x-intercept and 'b' is the y-intercept.





Multiply through by 35 to clear the fractions:

The x and y intercepts of a straight line are 5 and - 7 respectively. Find the equation of the line.
----------
| x   y   1|
| 5   0   1| = 0
| 0  -7   1|
--------------------

x*(0 + 7) - y*(5 - 0) + 1*(-35 - 0) = 0
7x - 5y = 35
