2y - 4x = -12 2y = 4x - 12 At the x-intercept, y = 0. 0 = 4x - 12 0 = x - 3 x = 3
-4a = 48 a = -12
It is a linear equation. The highest power of x in the equation is 1 (3x1-4=12) so its "degree" is 1, and equations of "degree 1" are called linear equations.
It is: 6
It is a linear equation in a single variable, x.
It is a simple linear equation in a single variable, n. And, in case you are wondering, n = 12.
It is one linear equation in two unknown variables: e and a.
If: 12 = 9x+3 Then: 12-3 = 9x And: 9 = 9x So: x =1
For x-intercept, y = 0 so -4x = -12 therefore x = 3.
6x+5k=12
An equation
12
If: 2y-4x = -12 Then: y = 2x-6 So the y intercept is -6 and the slope is 2
