Answer:
m=1/2 b=1
Step-by-step explanation:
y=mx+b
The y-intercept is b, and the slope is m.
Let's see, the slope is rise/run. the first coordinate is (0,1) and the second is (4,3). 2/4 would be 1/2, so the slope would be 1/2. S0, m is 1/2.
y-intercept is the starting point. We can easily see that the y-intercept is 1, because the first point was (0,1).
so the final equation: y=1/2x+1
