Answer:
y = 4/3x + 1
<u>Hope this helps :)</u>
Step-by-step explanation:
The slope-intercept form is y = mx + b.
m = the slope which is 4/3
b = the y-intercept which is 1
So to substitute the numbers in, the final equation would be y = 4/3x + 1
4x - 5y + 20 = 0
<u> - 20 - 20</u>
4x - 5y = -20
4x - 4x - 5y = -20 - 4x
-5y = -20 - 4x
<u>-5y</u> = <u>-4x - 20</u>
-5 -5
y = ⁴/₅x + 4
The slope would be ⁴/₅.
This will be a third degree polynomial since we have 3 zeros. We will FOIL them out. They are: (x-2), (x+7i), (x-7i). The product of the second and third factors gives us
. i^2 = -1, so if we simplify, we have
. Now we will multiply that with x-2 to get
. There you go!
Add them all up then divide by 5, so it should be 666.43
