The number of marks scored by Mini for 11 correct answers that she got would be 22 marks.
How to find the marks scored ?
To find the marks scored, you need to find the equation of the line. Fist fine the slope by picking two points on the graph such as ( 2, 4 ) and ( 8, 16 ).
The formula for the slope is:
= Change in y / Change in x
= ( 16 - 4 ) / ( 8 - 2 )
= 12 / 6
= 2
This means that for every correct score one gets, they will get 2 marks scored. If Mini had 11 correct answers, the score would be:
= 11 x 2
= 22 marks
