Question

A line with a slope of 3 passes through the point (2,5) what is the equation of this line?

Answer 1

Slope of the line equals 3 at the points (2,5) so m=0
The equation is a horizontal line, therefore the slope is 0.

Answer 2

y=3x-4 because the form of a line's equation is y=mx+b where m is the slope or three in this case and b is the value of y in the y intercept and in this case it is -4 so you get y=3x+(-4) or y=3x-4.
