Answer:   \bold{\{-2, \dfrac{5}{2}\}}

<u>Step-by-step explanation:</u>

2x² - x - 10 = 0

Replace -x with 4x - 5x and factor using Grouping Method:

2x² + 4x  -5x - 10   = 0

2x<u>(x + 2)</u>  -5<u>(x + 2)</u> = 0

(2x - 5) (x + 2) = 0

2x - 5 = 0   and    x + 2 = 0

2x = 5         and    x = -2

x = 5/2

Answer:

y = -1/2x - 2

Step-by-step explanation:

The line is negative, so the slope has to be negative. (-1/2)

You would use the equation to find the first point to plot. -1/2 times 0 is 0. 0-2 equals -2. This means that the first point would be (0,-2). This proves that the correct equation is <u><em>y = -1/2x - 2</em></u>.
