Answer:
y = 5
Step-by-step explanation:
The slope formula is y - y divided by x - x.
So, we put together numbers we already know:
[tex]\frac{y-3}{2-1}=\frac{2}{1}[/tex]
(2 is also equal to 2/1)
So, now we have to think what minus 3 equals 2?
5
HOW TO CHECK IF THIS IS CORRECT:
[tex]\frac{5-3}{2-1}=\frac{2}{1}[/tex] ✔
