Answer:
y = 3x + 4
Explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here slope m = 3 , then
y = 3x + c ← is the partial equation
to find c substitute (- 2, - 2 ) into the partial equation
- 2 = 3(- 2) + c = - 6 + c ( add 6 to both sides )
4 = c
y = 3x + 4 ← equation of line
