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


m = (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 = (y_(2)-y_(1))/(y_(2)-x_(1))


m = (-0.2 - (-0.25))/(1-0)


m = (-0.2 + 0.25)/(1-0)


m = (0.05)/(1)


m = 0.05 (The last answer)

Answer:

Option 4th is correct

Slope is, 0.05

Explanation:

Slope formula is given by:


\text{Slope} = (y_2-y_1)/(x_2-x_1) ....[1]

From the given table;

Consider any two points i.e,

(-2, -0.35) and (-1, -0.3)

Substitute in [1] we have;


\text{Slope} = (-0.3-(-0.35))/(-1-(-2))


\text{Slope} = (-0.3+0.35)/(-1+2)


\text{Slope} = (0.05)/(1)

Simplify:


\text{Slope} = 0.05

Therefore, the slope of the line represented by the points in the table is, 0.05
