Answer:
Explanation:
b is the y intercept. Start with b. The graph shows that the point (0,b) is (0,1)
So far what you have is y = mx + 1
Now you have to deal with m
m = (y2 - y1)/(x2 - x1)
m = (1 - 0)/(0 - -1/2) = 1 /0.5 = 2 Use your calculator for this.
So the line is y = 2x + 1
As you move into the shaded area y > 2x + 1
I reproduced the graph to show that pointed the arrow in the right way. You can try it to see if it works by trying a couple of points. y should work out to be greater than 2x + 1
