1. for the function rule y = -2x - 3, provide the x-y coordinates of the y-intercept and the x-intercept. show your work.

The function is y=f(x)=-2x-3 

the graph of this function are all pairs (x, y)=(x, f(x))=(x, -2x-3)

the y-intercept of a graph of a function, is the point where the graph cuts the y-axis, which happens at x=0.

at x=0, f(x)=f(0)=-2*0-3=-3

the x-intercept(s) of the graph, are the point(s) where the graph intersects the x-axis. At those points, the y-coordinate is 0.

so the x-intercept(s) are points of the form (x, 0)

now, 

 (x, 0)=(x, -2x-3)

0=-2x-3
2x=-3
x=-3/2

 

x-intercept: (-3/2, 0)
y-intercept: (0, )

Answer:

$4034.40

step-by-step explanation:

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
