Answer:
-1
Step-by-step explanation:
What you're gonna do is plug in the values. (i rhymed) The formula is y=mx+b
m = slope
b = y-intercept
y and x are just the y and x values.
1 = 2(1) + b
1 = 2 + b
-2 -2
-1 = b
That's how you solve for the y-intercept (b) = -1.
Hope this helps and have a great day!
