What is the Slope of the line described by the equation y equals 4x - 2?

Answer 1

2

Answer 2

Slope = 4

Edit 1

The slope of a line is always the number you multipy X by.

Re-edit

The "always" part in the above statement is not correct. The slope is the coefficient of X only if the equation is written in the standard slope-intercept from. For linear equations written in other, equally valid, forms it is not true.

For example, to avoid fractions, a linear equation may be written as

2y = 3x + 6. The number multiplying X is 3 but the slope is 3/2.

A second example:

Equations may be written in the form 2x + y = 3. This form is particularly useful when the equation is either generalised to or derived from 3-dimensional coordinate geometry. Again, the coefficient (or multiplier) of X is 2, but the slope is -2.
