x^2-9x+18=0

Factoring, we have:

(x-6)(x-3)=0
So x can be 6 or 3.

What is the slope of the line represented by the points in the table?
kotykmax [81]

To find the slope(m) of the line, you can use the slope formula:

m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

and plug in 2 points.

You can use any of the points, I will be using the points (0, -0.25) and (1, -0.2)

m = \frac{y_{2}-y_{1}}{y_{2}-x_{1}}

m = \frac{-0.2 - (-0.25)}{1-0}

m = \frac{-0.2 + 0.25}{1-0}

m = \frac{0.05}{1}


m = 0.05  (The last answer)
