D.-9

astrophysics · Answer

You can use the slope formula, where m represents the slope and your points are $$(x_1,y_1)~~~\text{and}~~~(x_2,y_2)$$$$m = \frac{ y_{2}-y _{1} }{ x _{2}-x _{1} } $$

So it's D ? @astrophysics

astrophysics · Answer

Why

anonymous · Answer

According to the given points's y values, the line is parallel to the x axis and is 5 units north of the x axis.
Maybe  C ?

aaronandyson · Answer

(-2,5) and (7,5)

Use the slope formula

$$slope = \frac{ y_2 - y_1 }{ x_2 - x_1 }$$

Slope is generally denoted by the letter $$m$$.

Here

$$x_1 = -2$$
$$x_2 = 7$$
$$y_1 = 5$$
$$y_2 = 5$$

Replace the letter with the number associated/representing it.

tejas21 · Answer

O ...as they both have same ordinate..they lie parallel to x axis

tejas21 · Answer

Hence they have tan0=0...any line parallet to x axis hqs slope zero
