It's an equation that can represent the graph of a
straight line with slope=3 and y-intercept = -14 .
y = 3x = 12y = 12
-9
3x-y=9 y=3x-9
y= -4x-7 y=3x 3x= -4x-7 3x+4x=7 7x=7 x=1
1) y - 7y = 36 -6y = 36 y = -6 We know that, y = 3x -6 = 3x x= -2 Conclusion, y= -6, x = -2
17
y=2/3x-7
y = 3x = 12y = 12
3x - y = 4 Get y by itself to see if it is the same as y = 3x - 4: 3x = 4 + y 3x - 4 = y Therefore, 3x - y = 4 is the equivalent of y = 3x - 4.
y = 15 (by transitivity)
-9
3x + 3y = 14 - 4xSubtract 3x from each side:3y = 14 - 7xDivide each side by 3:y = (14 - 7x) / 3
3x - y = 0 5y = 15 5y = 15 Divide by '5' on both sides Hence y = 3 Substitute for 'y' in the first equation./ 3x - 3 = 0 3x = 3 Divide both sides by ;3; x = 1 So in ( x,y) form the answer is ( 1,3).
3x-y=9 y=3x-9
3x + 7y = 14Subtract 3x from each side:7y = -3x + 14Divide each side by 7:y = -3/7 x + 2
y = 3x 3x + 4y = 30 3x + 4(3x) = 30 3x + 12x = 30 15x = 30 x = 2 y = 3x y = 3(2) y = 6 (2, 6)
y equals 3x has the greater slope.
