Answer :
Answer:
20
Step-by-step explanation:
we first find the formula of the line
y = mx+b
m = (y2-y1)/(x2-x1)
m = 10/10
m = 1
y = 1x + b
y = x + b
plug in points from the table
10 = -10 + b
20 = b
b = 20
b is the y-intercept
20
When there is a 0 in the x coordinate, you know it is a y-intercept, and vice versa.
