Answer:
y=1/2x-2
you write it in y=mx+b form
I 'll suggest you solve it on CY math calculator it even shows you steps and it is free and if yo got really big answer that's correct because I checked your question on CY math calculator it was really big and the answer was
y = 883.4235323892×<span><span>10^ -168
to confirm your answer is correct check it on CY math calculator .

Answer:
What is the question?
Step-by-step explanation:
Rewrite the given quadratic equation in standard form: Kx 2 + 2x - 1 = 0
Discriminant = 4 - 4(K)(-1) = 4 + 4K
For the equation to have two real solutions, the discriminant has to be positive. Hence we need to solve the inequality 4 + 4K > 0.
The solution set to the above inequality is given by: K > -1 for which the given equation has two real solutions.
