You can't. y = ex + b only applies to straight lines. Exponents produce curves. Quadratics produce parabolas, hyperbolas, and ellipses and the various forms have been worked out and are usually presented in courses for college freshmen. Higher order exponents are not so easily characterized.
The answer is y = -3x -4.
The straight line equation is: y = 2x
If you mean (6, 5) and (-8, -23) in the form of y = mx+b then it is y = 2x-7
m
If you mean: y = mx+c then m is the slope and c is the y intercept
The code is YMX
y=m*x+b is called the slope-intercept form because it describes a line where m is the slope and b is the point on the y-axis that the line intercepts.
If you mean: y = mx+b then the slope of the line is m and the y intercept is b
It rotates the graph about the point (0, b). The greater the value of m, the more steeply it rises to the right.
Read the calculator manual.
Because in a vertical line the slope is undefined, there is no "y" answer or "b" value and the line is in the form of x = some number such as x = 3 which is a vertical line.
If you mean: y = mx+b then m is the slope and b is the y intercept
