The equation of the line is y = 7x + 5 The gradient = the slope of the line = dy/dx = 7, in this case. The y-intercept is 5. ========================
-46 = 3x + 7x
7x + y = 8 Subtract 7x from each side of the equation: y = -7x + 8
y = 6/7x+3 General form of the line equation: 6x -7y+21 = 0
13x
It is 9x
x=6
-7x + 5 = -9 -7x = -14 7x = 14 x = 2
7x + y = 4y = 4 - 7x
7x is still the slope, no matter what x equals.
y = -7x + 6 is the equation of a straight line. It has a slope of '-7' and a y-intercept of '6'. For it to be parallel it must be compared to another line. e.g. y = -7x + 12 is a paralle line However, y = 7x + 6 is NOT a parallel line, because the slope is in a different direction.
