Answer:
Slope intercept form: y = 4x + 14
Slope: 4
Y-intercept: 14
Step-by-step explanation:
y - 2 = 4(x + 3)
Use distributive property
y - 2 = 4x + 12
y - 2 + 2 = 4x + 12 + 2
y - 0 = 4x + 14
y = 4x + 14
Legnth of 1 section times number of sections=number of feet needed=6*12=72
72ft=850
divie both sides by 72
1ft=11.8055555
1 ft=$11.81
The point would be (-4,-9) im pretty sure
2
Divide both the top and bottom by 2 and you get 2/3
12x+2y=112
6x+y=56
6x=56-y
x=(56-y)/6
y=(56-6x)
