Answer is D (-2) You have to find 2 points on the graph where it’s actually plotted at a point. From one point to another it goes down 2 the over to the right 1. Use the term “rise over run” to set this up as 2 over 1 (2/1) and the graph is going negative so the answer would be -2
For this you count rise over run aka how many up divided by how many over starting from 0. here it’s 7 up and 3.5 side, 7 divided by 3.5 is 2 and the line is going down so it’s negative 2 (D)
Divide the number of questions she got correct by the total number of questions on the test them multiply the decimal answer by 100 to get the percent.
