What are the factors of 3X and 21?
1, 3, X 1, 3, 7, 21 If that's 3x + 21, it factors to 3(x + 7)
What is the slope of -7y plus 21 equals 3x?
-7y + 21 = 3x Add '7y' to both sides 21 = 3x + 7y Subtract '3x' from both sides 21 - 3x = 7y 'Swop around'. 7y = -3x + 21 Divide both sides by '7' y = -(3/7)x + 3 The slope of a straight line is the coefficient of 'x' In this case it is ' -3/7'.
