Answer:
(0,1.5)
Explanation:
The y-intercept is what the value of y is when x is at 0.
If you look at the graph when x is at 0, it appears to be 1.5.
Of course, this can also be calculated.
The slope formula is change in y divided by change is x.
One point that can be clearly seen is (1,3), and another is (-1,0)
(3-0)/(1-(-1)
3/2
Now you can plug it in!
(0)=-1(3/2)+b
Add 3/2 to the other side
b=3/2=1.5
