Linear Equations in Slope-intercept Form

Question

A line has a slope of 3 and passes through the point  (6,43)

write it in slope-intercept equation

Answer 1

y= mx + b

y = 3x + b

43 = 3(6) + b

43 = 18 + b

43 - 18 = 18-18 + b

25 = b

y=3x + 25

Answer 2

Start with point-slope form

y - 43 = 3(x - 6)

Can you simplify and convert to slope-intercept form?
