7x + 4 = - 6
7x = - 10
x = - 10/7
X-intercept: x = - 10/7
There is no y-intercept. The graph is a straight vertical line passing through the point x=-10/7.
It's parallel to the y-axis, so it never intercepts the y-axis.
-46 = 3x + 7x
7x + y = 8 Subtract 7x from each side of the equation: y = -7x + 8
It is 9x
-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
-7x - 2y = -3
