Answer:
Step-by-step explanation:
use the point slope equation.
y-y1 = m(x-x1)
the point is (x1, y1) = (2, -1)
the slope is m = -3
y+1 = -3( x-2)
y = -3x +6-1
y = -3x +5
Y = -3x -1
Y = mx + b
Y is the y intercept (x,y) always graph on y axis
M is the slope

Range y≥-3
(-5)+(-4)= -9
(-3)+(+1)= -2
(-2)+(-7)= -9
