m=-2,(3,-7)

Answer by KMST(5328) (Show Source): You can put this solution on YOUR website!
In the x-y plane, the equation of a line that is not "vertical" can be written, in the form, as
The number is the , and is the .

PROBLEM # 1
If a line passes through the point (-1,0) and has the y-intercept ,
its equation will be
We just have to find .
THE SIMPLE WAY:
We know that the point (-1,0), with and
belongs to that line, so we substitute those values for and tp get
--> -->
The equation for that line is with and , so it is

PROBLEM # 2
If a line has a slope of ,
and passes through the point (3,-7), with and ,
the equation of the line in slope-intercept form will be with some .
ONE WAY:
We can find by substituting the coordinates of the point (3,-7) given
--> --> -->
So the equation is
ANOTHER WAY:
The equation of a line with slope .
that passes through point P(,) is
in form
Substituting the coordinates of our point P(3,-7),
and
we get
--> --> -->
