Plot a graph of y-axis against x-axis.
The graph should be a straight line passing through:
(-2,0.8) , (-1,-0.4) , (0,0) , (1,0.4) and (2,0.8)
Answer:
The slope is 3
Step-by-step explanation:
We can find the slope by using
m = (y2-y1)/(x2-x1)
= (11 -2)/(6-3)
= 9/3
= 3
Answer: a= -3
a+3=-2
a=-3
2
I dont know for sure though...
