When you graph the equation [ y = 7x ], the graph is a straight line that passes throughthe origin and has a slope of 7.The x-y coordinates of every point on the line are an ordered pair that satisfies the equation.There are as many of them as there are points on a line ... an infinite number.Here are a few of them:(0, 0)(1, 7)(0.2, 1.4)(-9, -63)(137, 959)

7x - 4 = 60 7x = 64 x = 9.14
-7x + 5 = -9 -7x = -14 7x = 14 x = 2
If x=2, then 7x = 14 and if y=5 then 4y=20.
y=7x
-46 = 3x + 7x
