Question

What is the slope of the line in the given graph?
A) 1/2 B) -1/3 C) 3 D)-3

Answer 1

c) 3

Explanation:

The first step is to see if it is positive or negative. since it is going upward and to the right, it is positive, if it is going upward and to the left it is negative. So since it is positive the answer is either a or c. Now that we have our 2 points we need to calculate how far they are. Whenever measuring the distance of 2 points, look how many units it's above or below, then divide by the units it's to the left or right. So for this, it takes 3 points to go up, then 1 point to the side. We don't calculate 1 to the side and 3 down. We always calculate if it goes up and down, and then to the sides.

Answer 2

We find the slope through the formula y2-y1/x2-x1
so when we plug in the values of our two points, we get
2-(-1)/(0-(-1))
this gets us 3/1
Which gives us the slope m=3
