I think you're supposed to substitute -5 into x. So now the equation is
f(-5)= 6(-5) +7.
f(-5)= -30+7
f(-5)= -23
As a result, the value of f(-5) is -23
Solution:
Coordinates of Point E and F are (-2,4) and (5,10).
Suppose the Point M(x,y), divides the Line Segment Joining E (-2,4) and F (5,10) in the 7:3 ratio.
So, EM: MF= 7:3
Formula for internal Division


So,we get
x= 2.9
and , y= 8.2
there is no triangle drawn
The answer is D. Quadrant I, as both the X and Y coordinates are positive.
