X + 7x = 56 + 8
Simplifying x + 7x = 56 + 8 Combine like terms: x + 7x = 8x 8x = 56 + 8 Combine like terms: 56 + 8 = 64 8x = 64 Solving 8x = 64 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Divide each side by '8'. x = 8 Simplifying x = 8
Quick answer A <<<<
All horizontal lines have an equation of
y = k where k is a number. k is the y intercept.
Here are a few lines drawn for you.
y = 3
y = 1
y = - 1
y = - 2
In y = ax + b the term ax disappeared. The graph shows that x is not zero. It has many values. So the m must be zero.
