Answer:
127
Step-by-step explanation:
n = 7
slope = y2-y1 / x2-x1=
-1 -5 / 2 - -1 = -6/3 = -2
slope = -2
y intercept = y =mx +b
y = -2x +b
y=-2*-1 +b
5 = -2 +b
b = 5-2
b =3
y intercept = 3
Answer:
The value obtained by dividing the change of y coordinate by the change of x coordinate is called slope
