Can someone help me with this math problem?? I barely understand it and just need help.

Answer:
The -intercept is 100
In coordinate form it is (0,100)
The equation is y = 1/2x + 100
Step-by-step explanation:
Use the formula y = mx+b
m is the slope and b is the y intercept
This is the point where it crosses the y axis (up and down)
I hope this helps!
