Answer: The line already goes thru 6,2 because 6=1/3(2) So the equation is y=1/3x
Step-by-step explanation:
(y-2)=1/3(x-6)
y-2=1/3x-6/3
y=1/3x
Point-slope formula;
y - y1 = m(x - x1) given point(-1, 4) and slope(m) is 4.
y - 4 = 4(x - (-1)
y - 4 = 4x + 4
y = 4x + 4 + 4
y = 4x + 8 << the equation.
hope this helped, God bless!
