Answer:
Step-by-step explanation:
It's already in a form that only ha positive exponents. Just to state it though you could rewrite it as or
The question asks for positive exponents though so yu don't need to do that.
You also need to know so in this case
so
To write the equation of line in y = mx + b form, we need
to identify the slope of the line and the y-intercept.
I would start by setting up a coordinate
system and plotting both points.
I have shown this below.
Let's start with our first point, (3, -1) which we call point A.
Now our second point, (6, 1) which we call point B.
To get from point A to point B, we rise 2 units and run 3 units.
So we know that our slope is 2/3.
However, we need the y-intercept.
Remember, this is the point where the line crosses the y-axis.
Since point B is farther from y-axis,
we need to go in the other direction.
So starting at point A, we go down 2 and to the left 3.
Remember, -2/-3 is 2/3 since a negative/negative = positive.
Now plot point C.
Notice that point C is on the y-axis.
It has the coordinates (0,-3).
Now we know our slope and y-intercept.
So our equation reads 2/3x - 3.
The slope is positive since the line is going up.
