Answer:
y = 3x - 11
Explanation:
the equation of a line in gradient- slope form is
y = mx + c ( m is the gradient and c the y- intercept )
here m = 3 , then
y = 3x + c ← is the partial equation
to find c substitute (6, 7 ) into the partial equation
7 = 3(6) + c = 18 + c ( subtract 18 from both sides )
- 11 = c
y = 3x - 11 ← equation of line
