➷ Substitute the value for 'x' in every time you see x
1) y = -2(-2) + 6
y = 10
2) y = -2(0) + 6
y = 6
3) y = -2(2) + 6
y = 2
4) y = -2(4) + 6
y = -2
5) y = -2(6) + 6
y = -6

Answer:
The slope is -2
Step-by-step explanation:
y+6=24-2x
Subtract 6 from each side
y+6-6=24-6-2x
y = 18 -2x
Rewriting
y = -2x+18
This is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
The slope is -2 and the y intercept is 18
Answer:
The volume of the cylinder is 9.42ft³
Step-by-step explanation:
radius = half of diameter
r = 2ft /2 = 1ft
To calculate the volume of a cylinder we have to use the following formula:
v = volume
h = height = 3ft
π = 3.14
r = radius = 1ft
v = (π * r²) * h
we replace with the known values
v = (3.14 * (1ft)²) * 3ft
v = (3.14 * 1ft²) * 3ft
v = 3.14ft² * 3ft
v = 9.42ft³
The volume of the cylinder is 9.42ft³
