Answer:
-1 <---------- slope
Explanation:
Since the formula is y2-y1=x2-x1
since the points are (-2,6) and (0,4)
Enter the points in
4-6/0-(-2) ----> (2 negatives is a +)
-2/2= -1
The slope is -1
If the slope is -1, the equation will be y=-x+b
then, enter one of the given points, (-2,6)
6=2+b
b=4
So the slope int form is y=-x+b
to find the point slope form,
y-y1=m(x1-x) <--- formula
So,
take 1 point (-2,6) and enter it in
y-6=-1(x+2) <--- point slope form
to graph y=-3x+2
make x=0 and enter into the equation
y=0+2
y=2
so if x=0, y=2 so thats one point (0,2)
and lets say if x=-6 (enter into equation)
y=-3(-6)+2
y=18+2
y=20
so if x=-6, y=20 (another point) (-6,20)
you only need 2 points to graph a line
so enter (0,2) and (-6,20) and draw a line
