(-3, 0) and (-2,2)
now, we can plug these values into formula
and we get
(b)x = -2 to x =1
Firstly, we will find points
(-2,2) and (1,-4)
now, we can plug these values into formula
and we get
(c) x = 0 to x =1
Firstly, we will find points
(0,-3) and (1,-4)
now, we can plug these values into formula
and we get
(d) x = 1 to x =2
Firstly, we will find points
(1,-4) and (2,0)
now, we can plug these values into formula
and we get
(e) x = -1 to x =0
Firstly, we will find points
(-1,0) and (0,-3)
now, we can plug these values into formula
