Answer: Your slope would be -2.
Explanation:
So for this, I'm going to use the points (-5,10) and (-3,6).
The regular slope formula is Y2-Y1 over X2-X1. (Make it like a fraction with the Y2-Y1 as the numerator and the X2-X1 as the denominator.)
The first part is to substitute your 2 coordinates into each variable.
Y2 - Y1 = 6 - 10 = -4. | X2 - X1 = (-3) - (-5) = 2.
The second part is to divide the -4 you got from the y-coordinates, by the 2 you got from the x-coordinates.
And a rule when dividing negative numbers is that if you divide a negative by a positive, the quotient is going to be negative.
Thus, your slope is -2.
