Answer: The slope is 5
Step-by-step explanation:
You can calculate the slope of the line with this fomula:

Given the points (2,3) and (1,-2), you can identify that:

Now, the final step is to substitute these values into the formula
, getting that the slope of this line is:


Answer:
x^2 -3x +15
Step-by-step explanation:
7x^2 +6x -9x - 6x^2 +15
Combine like terms
7x^2 - 6x^2 +6x -9x +15
x^2 -3x +15
