Answer:
y = - 3x + 14
Explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given slope m = - 3 , then
y = - 3x + c ← is the partial equation
to fnd c , substitute (3, 5 ) for x and y into the partial equation
5 = - 3(3) + c = - 9 + c ( add 9 to both sides )
14 = c
y = - 3x + 14 ← equation of line
