Answer:
(0,-4)
(1,-6)
Step-by-step explanation:
2x+y = -4
y = -2x - 4
f(x) = -2x -4
either use the table function on a standar fx-991ES Plus calculator, or just substitute values of x to get the values for the y co-ordinate,
where x = -1
y = -2(-1) -4
y = -2
hence at x = -1, y = -2 . co-ordinates = (-1,-2)
and starting at -1 , doing this for numbers till 3 we get
(-1,-2)
(0,-4)
(1,-6)
