Answer:

y = 3x - 5

Step-by-step explanation:

The equation of a line with slope m that passes through the point (x1, y1) can be calculated as:


y-y_1=m(x-x_1)

So, replacing the slope m by 3, and the point (x1, y1) by (3, 4), we get:


y-4=3(x-3)

Finally, to write the equation in slope-intercept form, we need to solve for y, so:


\begin{gathered} y-4=3(x)-3(3) \\ y-4=3x-9 \\ y-4+4=3x-9+4 \\ y=3x-5 \end{gathered}

Therefore, the answer is y = 3x - 5
