7x + y = 6 y = 6 - 7x dy/dx = 0-7 = -7 Slope = -7
If you mean: 7x-3y = 21 then y = 7/3x-7 whereas -7 is the y intercept and 7/3 is the slope

The equation y = 7x represents a linear relationship where the value of y is always 7 times the value of x. Therefore, all ordered pairs for this equation will have y as a multiple of 7x. For example, when x = 1, y = 7; when x = 2, y = 14; and so on. The ordered pairs for y = 7x will be in the form (x, 7x).
