How do you write the equation of line given x-intercept of 4 and a slope of 3/4?
The equation of a line in
where m represents the slope and b, the y-intercept.
Here we have a coordinate point (4 ,0) and
So the partial equation is
#y=3/4x+b#and to find b we substitute x = 4 and y = 0 into the partial equation.
#rArry=3/4x-3" is the equation"#
We are told that
the x-intercept is
If the x-intercept is
this means that
So our general equation:
and our equation is
Using the above logic we can see that the general case when given
a slope of
an x-intercept of
