Answer:

Step-by-step explanation:
The point-slope form of a line is given as:

Where
m is the slope
is the x-coordinate of the point given (passing through the line)
is the y-coordinate of the point given (passing through the line)
Now,
Given,
Slope = m = 3
= 1
= 2
Now, we simply plug these into the formula for point-slope form of a line:

This is the point-slope form.
The way we simplify this is by using the distributive property and multiply every term by 0.5. When we do this we get 2a+3b
