What is the slope?<br><br> A) 3/7<br> B) 7/3<br> C) -3/7<br> D) -7/3
Brut [27]

Answer:

B) 7/3

Step-by-step explanation:

To find the slope of a line using a graph, locate two points. In this example, the points are (0, -2) and (3, 5).

Then, find the distance between the two points. To do so in this example, find the difference between 0 and 3, and -2 and 5.

3 - 0 = 3

5 - (-2) = 7

Since we're dealing with slope, the answer will be in y/x form. 7 is the distance between the y-coordinates and 3 is the difference between the x-coordinates, the answer is 7/3.
