Answer:
y = 3x - 2
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 (3, 7 ) into the partial equation
7 = 3(3) + c = 9 + c ( subtract 9 from both sides )
- 2 = c
y = 3x - 2 ← equation of line
