Question

The slope formula can be used to find the slope, m, of a line with points (L1, y1) and (22, 42).
Y2 – Yi
22 – 21
m
Which is an equivalent equation?
O Y1 = -m (22 – x1) + y2
yı = -m (x2 – 21) – Y2
Oyı = m (22 – 21) + y2
Oyı = m (22 – 21) – Y2

Answers

  1. Answer: (y-y_1)=m(x-x_1)\ or \ (y-y_2)=m(y-y_2)

    Step-by-step explanation:

    Point slope form: (y-b)=n(x-a) , where n=slope , (a,b) is the point through which line passes.

    If slope of the line = m and line passes through (x_1,y_1) and (x_2,y_2) :-

    (y-y_1)=m(x-x_1)\ or \ (y-y_2)=m(y-y_2)

    So, the equivalent equations are :

    (y-y_1)=m(x-x_1)\ or \ (y-y_2)=m(y-y_2)
