Answer:

\frac{-1+135i}{2}, \frac{-1-135i}{2}

Step-by-step explanation:

you use the quadratic equation:  (-b ± \sqrt{b2 - 4ac}) ÷ 2a

in this case, a = 5, b = 5, c = 8

inside the radical will be -135, hence using 135i where 'i' equals -1

Which equation matches the graph
Alina [70]

Answer:

C

Step-by-step explanation:

You can see from the graph that everytime x goes up by 1, y goes down by 4, so the slope is -4.

The y-intercept is at -1

This means that the equation would be C. y = -4x - 1
