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:
1.)88
2.)124
3.)3256
4.)102357
5.)79
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
The equation is (2x+5)^2.
It can't be A because 2 is the multiplier for only x.
It can't be C because the square is outside of the equation.
It can't be D because again, the square is outside of the equation.
So the only thing left is B.
