Answer:
The answer is in the photo.
Step-by-step explanation:
Slopes are represented using:
y = mx + b
_______
m - the slope, represented by a fraction or whole number

x - x, don't plug in the x-value
b - where you start on the y-axis
_______
On the left is the original slope. You apply the same slope to (5,-1). You don't have to apply the b.
So, all you have to do is start at (5,-1) and apply the angle, going up 8 and right 3.
