Look at the coefficient of the x term: the gradient of y = 3x + 12 is 3.
An equation in the form:
y = mx + c
is such that the gradient and y intercept can be read directly from it:

An equation such as y = mx + c is said to be in standard form. From such an equation, Gradient = coefficient of x = 3
y=-4x + 3 or generally y=mx + b so m, or gradient = -4
To find the gradient of the equation 2y = 4x + 1, we first need to rewrite it in slope-intercept form, y = mx + b, where m is the gradient. Dividing by 2 on both sides gives y = 2x + 0.5. Therefore, the gradient is 2.
x = -½
y=3x+2 so the gradient or slope is 3
