\tt Step-by-step~explanation:

To solve, we need to write this in slope-intercept form.


\tt Step~1:

Slope: 3

Point: (1,2)

Slope-intercept form:

y = mx + b (y = y value, m = slope, x = x value, b = y-intercept)

y = 2, m = 3, x = 2, b = ?

We have to solve for b. To do so, we plug in all these values into our formula. Move all values not equal to b to the left of the equation.


\tt 2 = 3(1)+b\\2=3+b\\2-3=3-3+b\\-1=b


\tt Step~2:

Now that we know what b is, we can plug it into our equation. Plug in only the value of the slope and the y intercept.

y = mx + b

y = 3x - 1


\large\boxed{\tt Our~final~answer:~y=3x-1}
