Answer:
y intercept=15 and slope is 3
Step-by-step explanation:
Ok so for this one we know the y intercept is 15 because the y intercept is wherever x=0 and in the table when x=0 y=15
to find slope we use (y2-y1)/(x2-x1) which when we put points (0,15) and (1,18) in for would be:
(18-15)/(1-0)
3/1
= 3
The following answer would have to be .34
20 to 30 is a 10% increase
The area is 2x^2+x-10 (the last one) Hope this helps!
