PLEASE HELP!!! LAST QUESTION
Which of the following is the equation of a line that passes through the points (2,5) and (4,3)

A. y= -2x+5

B. y= 2x+5

C. y= -x+7

D. y= x+7

Answer 1

the answer is c, or y= -x+7

Answer 2

The answer is C. y= -x+7
To get this answer, I just substituted the x values of the given coordinates in each of the equations to see which one would produce the given y values. y= -x+7 works because:
5= (-2)+7
3= (-4)+7
