Riley makes a mistake in step 2 while doing her homework. What is the mistake?
2 answers:
We have been given work of Riley. By looking at his work carefully, we have to identify the error. So let's start from beginning.
First line is just the question so there will be no error.
After that we try to factor denominators
STEP1:
Factors are correct so no error in step1.
In step2, we have to find the common denominator which will be (x-2)(x-3)(x+3)
so that means she needs to multiply and divide 2nd term by (x-2)(x-3) while she multiplied by only (x-2). Which means she used wrong common denominator.
<u>Hence final answer will be "B. She used the wrong common denominator."</u>

Given:
The equation of a linear function is:
To find:
The y-intercept and slope of the given equation, then draw the graph of the equation.
Solution:
Slope intercept form of a line is:
...(i)
Where, m is the slope and b is the y-intercept
We have,
...(ii)
On comparing (i) and (ii), we get
Therefore, the y-intercept is -1 and the slope of the line is .
It means the graph intersect the y-axis at point (0,-1) and having slope . So, the graph of the equation is shown below.
