7x+y=6
y intercept when x=0
7(0)+y=6
0+y=6
y=6
line crosses y axis at (0,6)
(0,2)
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
It is 9x
13x
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.
7x+7=28x 28x-7x=7 21x=7 x=3
