-7x - 2y = -3
When the equation is given in the standard form: y = mx + c, the gradient is m. So here, y = 7x + 2 means m, the gradient, is 7.
7x + 2 = 6x + 2 if and only x = 0.

x = 8
The standard form is 7x + 2y - 3 = 0
-7x - 2y = -3
The expression can be simplified to: 7x+4y
The expression can be simplified to: 7x+4y
y = 6/7x+3 General form of the line equation: 6x -7y+21 = 0
7x + y = 8 Subtract 7x from each side of the equation: y = -7x + 8
x2 + 7x = 2x2 + 6 x2 - 2x2 + 7x = 6 -x2 +7x - 6 = 0 or alternatively x2 - 7x + 6 = 0
7x = -3y + 12
It is: y = -7x+1 in slope intercept form
y = mx + b is standard form where m = slope and b = y intercept y = 7x + 3 b = 3 = y intercept
23
It is: y = -3.5x+2.5 in slope-intercept form
