Question from Thomas, a student:

I'm attempting to get this in standard form


Hi Thomas,

I would first write the equation in slope-intercept form, y = mx + b. You know the slope m = 3 so the line is y = 3x + b. To find b substitute the point you know x = 1, y = 5 into the equation and solve for b. Finally move the x-term to the left side of the equal sign to obtain the equation in standard form, Ax + BY = C.

I hope this helps,
