Question

Which equation represents a line that passes through (5, 1) and has a slope of ?

y – 5 = (x –1)
y – = 5(x –1)
y – 1 = (x –5)
y – 1 = 5

Answer 1

y – 1 = (x – 5)

If you have y – 1 = (x – 5) and add 1 to both sides, you will end up with y = (x –5) + 1. Next, you will combine like terms to get y = x – 4. If you substitute in (5,1) the equation is 1 = 5 - 4, which is a true statement.
