Answer:
y = - 2x - 7
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 = - 2 , then
y = - 2x + c ← is the partial equation
to find c , substitute the point (- 2, - 3 ) into the partial equation
- 3 = - 2(- 2) + c = 4 + c ( subtract 4 from both sides )
- 7 = c
y = - 2x - 7 ← equation of line
