Answer:

-1 <---------- slope

Step-by-step 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

18 ft* (1 piece/ 1 1/3 ft)= 13.5 pieces.

Mr. Gengel can only cut 13 pieces from the big board (because we don't have half a piece)~
