I will give you branilest! All the graphs in this activity show points where both coordinates are positive. Would it make sense for any of them to have one or more coordinates that are negative?

*You do NOT have to type in the answer to the question above.*

2. The equation of a proportional relationship is of the form y = kx, where k is a positive number, and the graph is a line through (0, 0). What would the graph look like k were a negative number?

*Answer this question in the space provided below.*

x = 3/8 +/- i(√5)/8.

Step-by-step explanation:

I can't see any list by this is the solution of the equation:

x^2 - 3/4x = -1/4

x^2 - 3/4 x + 1/4 = 0

Multiply by 4 to remove the fractions:

4x^2 - 3x + 1 = 0

x = [-(-3) +/- sqrt(3)^2 - 4*4*1)] / 8

x = 3/8 +/-√ (-5) / 8

x = 3/8 +/-  √5 i / 8
