To find the slope of the line through the points and , we can use the formula for the slope :

Here, and . Plugging in these values:

So the slope of the line is , which corresponds to option A!

Now, did you know that slope is a crucial concept in understanding linear relationships in math and science? It essentially tells us how steep a line is on a graph, whether it’s tilting upwards or downwards, and helps us understand how variables interact.

If you’re ever unsure whether your slope calculation is correct, a good tip is to always remember that for every increase in the x-direction, the result in y-direction can either go up (positive slope) or go down (negative slope). Common mistakes include mixing up the order of the points, so always keep and straight!
