use y - y1 = m(x - x1) m= 3, point(12,1) y - 1 = 3(x - 12) y - 1 = 3x - 36 y = 3x - 35

write out line equation y=mx+b if it passed thru point (12,1) this means this point is a solution to this line equation so for b where this point is infact a solution to this equation

You have a slope and you have a point...use the point slope formula y - y1 = m(x - x1) replace 'm' with 3...y1 with your y-value and x1 with your x-value y - 1 = 3(x - 12) y - 1 = 3x - 36 y = 3x - 35

u need to understand the principle of what a line is!! everypoint on the line is a solution to the equation of a line, that is how this line is generated

Well, let's use the form of an equation y=mx+b. We're already given m, so all we need to do is plug in, giving us 1=3(12)+b Solve, giving b=-35 and our final equation of y=3x-35
