Answer:
Step-by-step explanation:
(3,0),(4,1) ⇒ (x₁,y₁),(x₂,y₂)
to find the equation of the line
y-y₁= {(y₂-y₁)/(x₂-x₁)}(x-x₁)
y-0= [(1-0)/(4-3)] (x-3)
y-0 = 1/1(x-3)
y-0 = x-3
y= x-3+0
y=x-3
compare to y=mx+c, where m is the gradient and c is the intercept on y-axis
m=1, c=-3
∴the y-intercept of the line is -3

10 people got parts
Answer:
The percent increase is 20%.
Step-by-step explanation:
It's fairly simple.
Multiply 10 by (100/10) which is 10 to get 100.
Multiply 12 by 10 to get 120.
120 - 100 = 20
Gained 9 yards, then lost 22:
9-22=c
-13=c
Therefore, the football team lost 13 yards in overall change in field position. Meaning, the team didn't gain any yards, they lost 13.
