Answer:
Step-by-step explanation:
Start by using the slope formula, which is :
y2 - y1 / x2 - x1
Now, get your two points and figure out which number will be your x1, x2, y1, and y1 values. (1,-3) will be your x1 and y1 values, because that point comes first in the question. (3,-5) will be your x2 and y2 values.
Put these values in the right order into your formula, like so,and then solve.
-5 - (-3) / 3 - 1
-5+3 / 2
-2 / 2
= -1
This is a slope of -1.
