Answer: B.) y-1 = x-1
Step-by-step explanation:
The normal format for point-slope equations is
(y - b) = m(x - a) a is the x-value of the given coordinate, b is the y-value and m is the slope
Here, the slope is 1, so it is understood, and 1 always "disappears" when it is a factor
So substituting the values given
(y - 4) = (x - 1) The parentheses are unnecessary because there is no "m"
