Question

What is the equation of the line that passes through the point (4,3) and has a slope of 1

Answer 1

y-3 = x-4

y = x-4+3 = x-1

y =x-1 has slope = 1 and goes through the point (4,3)

the slope = the coefficient of the x term, if the equation is solved for y.

the coefficient of x is an implicit 1 in y=x-1
