ax + by + cz + ... = k
where x, y, z, etc are variables
and a, b, c etc and k are constants.
In the simple case of 2 variables, this becomes
ax + by = k which can be rewritten as y = mx + c (different c from the first equation above).
If it is a straight line, then the equation is linear.
yes
It is a straight line.
Linear equation.
A straight line.
The word straight doesn't really apply to an equation. However the graph of a linear equation is a straight line.
This is a straight line graph with the equation, y = n where n is any positive or negative number.
y=x2
straight line
A straight line on the Cartesian plane is the graph of a linear equation.
A function is an equation that is a straight line when plotted on a graph.
The equation has no slope. The graph of the equation is a straight line with a slope of -1 .
