11. y=-1/3x-4
Plug the slope into m in y=mx+b and then plug in your point and solve for b. You get C
12. Parallel means it has the same slope or the same m, so the -1/2 stays the same and you plug that and your point into the y=mx+b and solve for b again. You get D, y=-1/2x-9
13. Perpendicular means that the slope is the opposite reciprocal so you flip it and multiply it by -1. You then plug that in for your slope and plug in your points and you get A, y=9x+13
Each piece will be 6 inches, and there will be 7 I believe.
When you don't use or write the percent right.<span />
The formula of the area of the circle:
π × radius^2
In this case, given that the radius is 14 inches:
π × 14^2
=196π square inches
Therefore the answer is 196π square inches.
Hope it helps!
This would be represented by the function Y = -3x + 4 C:
just remember that your slope is your X value, and on a graph it is your rise over run. since -3 is your slope, you go down -3(your rise, you go down since it is negative) and over one. its a whole number instead of a fraction because -3/1 is simplified to -3. Your Y intercept is the added number in the end of the equation. Basically they are your values in the linear equation, which is Y = mx + b
