It give you two point, (2,4)(-1, -1).
f(x)=mx+b
2m+b=4
-m+b=-1
2m+b+m-b=5
3m=5
m=5/3
b=2/3
f(x)=5/3x+2/3
Answer:
6+2-3
Becuz u immediately can do the problem with lower numbers which makes it easier than adding big numbers like 8+36
QUESTION A
The given points are
and 
The slope can be found using the formula;

We substitute the point to obtain;

This simplifies to

Therefore the slope is 5.
QUESTION 2
A positive slope indicates a rising line
A negative slope indicates a rising line
A zero slope means the line is horizontal.
An undefined slope means the line is vertical.
The correct answer is
A. The line rises from left to right.
<span>The answer is It represents a nonlinear function because its points are not on a straight line.</span>
