determine the slope of a line passing through the points (2, 9) and (0.66, 9)

Question

accessdenied · Answer

Slope is given by:
$$ \large m = \frac{y_2 - y_1}{x_2 - x_1} $$  *

anonymous · Answer

We have to use the gradient and find an equation formula
$$M=\frac{y2-y1}{x2-}$$ <<gradient/slope formula
$$y-y1 = m (x-x1)$$ <<find an equation formula

$$M=\frac{9-9}{0.66-2}= \frac{0}{-1.44} = 0$$

now use the find an equation formula and sub in M=0 and one point (2,9) 
                                                                                                     x1,y1
