We can assume that it is aline
y=mx+b
m=slope
b=yintercpt
if you have th epoints (x1,y1) and (x2,y2)
slope=(y2-y1)/(x2-x1)
pick any 2 points
(1,2) and (2,5)
slope=(5-2)/(2-1)=3/1=3
y=3x+b
solve for b
sub a points
(x,y)
(0,-1)
-1=3(0)+b
-1=0+b
-1=b
the equation is y=3x-1
or infunction form
f(x)=3x-1
Answer:
143a + 221b = 1,651
Step-by-step explanation
143a + 221b = 1,651
1.Add the "a"s and "b"s together seperatly.
2.Then put them together in a equation.
3.The a you added together is 143a.The b you added together is 221b.
Answer: 5...
Step-by-step explanation:
Do like this
(y - 1)(y² + 2y + 1)
y³ + 2y² + y - y² - 2y² - 1
y³ - 1
This is end result
