y=-10x-4
it would be 10.9999999999 or 11.0
-46 = 3x + 7x
7x + y = 8 Subtract 7x from each side of the equation: y = -7x + 8
It's the equation of a straight-line graph. Every point on the line is a solution of the equation. There are an infinite number of them.
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
