<em>The formula for slope is </em> $\frac{rise}{run} = \frac{y2-y1}{x2-x1}$ <em>.</em>

Subtract y1 from y2. (y1= -1, y2 = 3)

3 - -1 = 4

Now subtract x1 from x2. (x1 = 4, x2 = -4)

-4 -4 = -8

Divide the difference between the y coordinates by the difference between the x coordinates.

$\frac{4}{-8}$ or 4 ÷ -8 = -0.5

<h2>Answer:</h2>

<u>The slope between the two points is </u><u>-0.5</u><u>.</u>

Hope this helps love :)

Answer:

12 seconds

Step-by-step explanation:

Given

$y = -2.5x + 30$

Required

Determine the time taken to reach the ground

For the paper to reach the ground, y = 0

So, we have:

$y = -2.5x + 30$

$0 = -2.5x + 30$

Collect Like Terms

$2.5x +0 = 30$

$2.5x = 30$

Divide through by 2.5

$2.5x/2.5 = 30/2.5$

$x = 30/2.5$

$x = 12$

<em>Hence:</em>

<em>Time taken is 12 seconds</em>

<h2>Answer:</h2>

This is a theorem called Converse of Alternate Exterior Angles that states that <em>if two lines are cut by a transversal and the alternate exterior angles are congruent, then the lines are parallel</em>. Moreover, this theorem is based upon the corresponding Angles Converse Postulate that states that<em> if two lines are cut by a transversal and corresponding angles are congruent, then the lines are parallel. </em>We don't need to prove this postulate, it's assume to be true. So our goal is to get corresponding angles congruent in order to use the corresponding Angles Converse Postulate,
