Answer:
a) y = x**2 - 3
Step-by-step explanation:
Let x = 0, then y = -3 or anything above (the unshaded area), so "a" fits.
Here we can use fact than we can multiply fraction by inverse of fraction instead of dividing it.
Inverse of 1/3 is 3/1
Lets multiply it

- its our result

your missing degree is 108.
i may not be right, if i'm not i am very sorry.
Answer:
y=x+20
Step-by-step explanation:
The y-intercept is 20, as the line is on the y-axis while x is 0. The slope would be 0, because the y and x values both increase by 10, so 10/10 which simplifies to 1. The result would be y=10/10x + 20 simplifying to y=1x+20, which is y=x+20.
Hope this helps!
