(-2,0),m=-3?
Question:find an equation of the line containing the given point and given slope
Answers:
y= -3x-2
-3x-y-6=0
y=-3x -6
u know m represents the slope of the equation which is -3
then put that into the slope intercept form: y=mx +b
it would look like y=-3x + b
now evaluate the value of the point (-2,0) to the equation y=-3x + b
it would be: 0= -3(-2) +b
0= 6 +b
move 6 to left
-6 = b
substitute b in the equation with the number
y= -3x -6
Therefore, the answer is y= -3x -6
DaMn i just finished my exams and already forgot the formulae wait i'll get my book :)..yea use the formulae
(y-y1)=m(x-x1)
ie . y minus y to the 2nd point that is 0 =m<slope>multiplied by 1st that is <-2>...
answer is 3x+y+6=0
...
:)
