10. 8x+4y=4. y=mx+b
-8x. -8x
4y=-8x+4
÷4. ÷4. ÷4
y = -2x +1
slope = -2. y-int= 1

11. slope is changing y over changing x
m = (y2 -y1)/(x2-x1) (0,-1) x1 = 0, y1=-1
(-4-(-1))/(-2-0) (-2,-4) x2 = -2, y2 = -4
(-4 + 1) / (-2)
-3/-2 = 3/2 answer is 3/2
12. b because negative cause it flip in x axis and it become flatter because of the fraction.
13. 2y =8-8x
÷2. ÷2 ÷2
y = 4 - 4x

Raymond wants to plow a garden that is 5 feet longer than it is wide and has a total perimeter of 170 feet. what are the dimensi
kirill115 [55]
If the Length is 5 feet longer than the width then we can say the width is X and the length is X+5. If the perimeter is 170 feet then we can calculate the perimeter as
X+(X+5)+X+(X+5)=170 feet
2X+2 (X+5)=170 feet
2X+2X+10=170 feet
4X+10=170 feet
4X=170 - 10 feet
4X=160
X=160/4
X=40
so the width of the garden is 40 feet and the length is 40+5=45 feet
