Answer:
c. y = -x + 5
Step-by-step explanation:
coordinates: (2,3) & (7, -2)
m(slope) = rise/run = (y2-y1) / (x2-x1)
= (-2-3) / (7-2)
= -5 / 5
= -1
therefore, y= -1x + b => y= -x + b
to find b:
taken coordinate: (2,3)
y= -x + b
3= -2 + b
3+2 = b
5 = b
(*even if we take the other coordinate, we'll still get the same value of b)
therefore y= -x + 5
