Answer:
First choice
Step-by-step explanation:
It passes through (4, 0) and (0, -4)
Slope = (0 - (-4))/(4 - 0) = 4/4 = 1
so y - 0 = 1*(x - 4)
x - y = 4
8x - 8y = 32

Answer:
I believe the answer is $2.25
Step-by-step explanation:
To figure this out, first you need to find 25% as a decimal. 25% as a decimal is .25 . Then, you multiply 9 by .25 . 9 * .25 = $2.25. You are saving $2.25 with the discount.
Hope this helps :)
Answer:
y = -2x -1
Step-by-step explanation:
slope intercept form is y = mx +b
m = slope, b = y intercept
point is given as ordered pair (x,y)
plug in slope into y=......
y= -2x+b
plug in the point
3 = -2 * (-2) + b
3= 4 +b subtract 4 on each side
b = -1
y = -2x -1
V=(4/3)(pi)(r^3)
r=7
Hope this’ll help
