Question 1188239: Have I correctly found the equation of relation using the point-slope or point-intercept equations on 2 problems below?
Problem 1:
m = 3/5, (0, 3)
(y-3) = 3/5(x-0)
5(y-3) = 3(x-0)
5y -15 = 3x-0
-3x+5y = 15 Is this the correct equation answer

Problem 2:
m= 1/4, (3, -1/4)
(y - (-1/4y) = 1/4(x-3)
y + 1/4 = 1/4 12/4
1/4x+y = 12/4 - 1/4
1/4x +y = 11 Is this the correct equation answer
Please show correct steps if I have done incorrectly. Thank you
