Question 273402
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.
