An equation of a line in the form y = mx + c is said to be
in the slope y-intercept form. In a equation like this, 'm' represents the slope of the
line, and c represent y-intercept of line, which is same as the y coordinate of the line
where it intercepts the x-axis.
The given equation
is:
2x + 3y - 9 = 0
It can be
converted into the intercept form in the following
steps:
3y = - 2x + 9
y =
(-2/3)x + 9/3
y = (-2/3)x +
3
The above is the equation of line is in slope y-intercept
form. In this equation value of m = -2/3, and value of c =
3.
Therefore:
Slope of the
line = m = -2/3
y-intercept of the line = c =
3
