Standard form: Ax+By=C
first put in slope-intercept form:
slope = (0+5)/(6-3) = 5/3
pick point D: 0 = 5/3(6)+b -> b= -10
slope-intercept form: y=(5/3)x-10
multiply both sides by 3:
3y=5x-30
put in standard form:
5x-3y=30
combine your like terms and get x by its self
Answer:
with what you didnt put a question anywhere
The quadratic equation with roots a and b is given by:

Here a=1/2 and b=-4.
So the equation is given by:

The quadratic equation is as shown above.
