9514 1404 393
Answer:
- steeper
- up (4 units)
Step-by-step explanation:
When the equation of the line is in the form ...
y = mx + b
the coefficient 'm' is the slope of the line, and the value 'b' is the y-intercept, the point on the y-axis where the line crosses.
We say the line is "steeper" when the magnitude of the slope is greater. Line B, with its slope of 7 will be steeper than line A, with its slope of 3.
the new slope is steeper
__
The y-intercept of line A is -3. The y-intercept of line B is +1, so it crosses the y-axis above the point where line A crosses. One could say that line B is shifted up, when referring to the y-intercept.

a-c. The area formulas for these figures are ...
rectangular prism: A = 2(lw +h(l+w))
cylinder: A = 2πr(r +h)
sphere: A = 4πr^2
d. The total will be the sum of products: area of each pillow times the number of that type
__
e-g. The volume formulas for these figures are ...
rectangular prism: V = lwh
cylinder: V = πr^2h
sphere: V = (4π/3)r^3
h. As with area, the total volume is the sum of products: volume of each pillow times the number of that type.
