Answer:
see explanation
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = and (a, b) = (3, - 2) , thus
y - (- 2) = (x - 3) , that is
y + 2 = ( x - 3) ← in point- slope form
(b)
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = , thus
y = x + c ← is the partial equation
To find c substitute (3, - 2) into the partial equation
- 2 = + c ⇒ c = - 2 -
= -
y = x -
← in slope- intercept form
