Wats the x-intercept of the line that has an equation of -3x+6y=9
The standard form of a line in the slope-intercept form is
y = mx + b.
In this form m is the slope and b is the value of y where the line intercepts the y-axis.
The line -3x+6y=9
can be rewritten as
6y = 3x +9
and finally as (dividing both sides of the equation by 6):
y = 3/6*x + 9/6
y = 1/2*x + 3/2
In this form the slope m = 1/2 and the y-intercept is 3/2.

y intercept is when x=0
x intercept is when y=0
-3x+6y=9
-3x=9
x=-3
(-3,0)
