Will give brainliest. 1.what is the equation of a line with a slope of 3 and a point (3, 1) on the line? express the equation in the form of y=mx+b where m is the slope and b is the y-intercept.

y = 3x -8

Step-by-step explanation:

I find it convenient to start with a version of the point-slope form of the equation for a line. That is, for point (h, k) and slope m, ...

y = m(x -h) +k

For your m=3 and (h, k) = (3, 1), this equation becomes ...

y = 3(x -3) +1

Eliminating parentheses puts this in the form you desire:

y = 3x -8
