Step-by-step explanation:
Given expression is x⁴-kx²+4 =0
x−2 is a factor of the given expression.
So, x=2
Substitute in the equation, we get
2⁴-k(2)²+4
⇒16+4k+4=0
⇒4k=−20
⇒k=−5

Answer:
- your graph is correct
- y = 3x -5
Step-by-step explanation:
The graph shows you the line has a "rise" of 1-(-2) = 3 for a "run" of 2-1 = 1, so the slope is 3/1 = 3.
The y-intercept is seen to be -5, so the equation is ...
y = mx +b . . . . . where m is the slope (3) and b is the y-intercept (-5)
y = 3x -5
__
The points and line are plotted correctly, so you already have your graph.
