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
