This can be
solved by solving the slope of the line. First let y be the rating of the test
and x be the number of incorrect answers. Slope can be solved using the formula:
M = ( y2 –
y1 ) / ( x2 – x1)
M = ( 90 –
98) / ( 5 -1 )
M = -2
<span>So the model
has a negative slope</span>
If the line graphed is a straight line, then that function is linear. If the line curves in any way, then it is not linear. Hope this helps!
Hey there! :D
Slope formula:
m= (y2-y1)/(x2-x1)
m= (0-(-7)/(4-4)
m=0+7/0
m=7/0
The rise is 7 and the run is 0.
I hope this helps!
