We first need to use the slope formula: %28y2-y1%29%2F%28x2-x1%29
Next we need to plug in our variables: %288-3%29%2F%282-1%29
That adds up to 5%2F1, or just 5.
Next we use the point slope form. y-y1=m%28x-x1%29
We can use either coordinate, so let's use the first one!
y-3=5%28x-1%29
Use the distributive property
y-3=5x-5
Add 3 to both sides:
y=5x-2
Final Answer: y=5x-2
