how to determine the slope of the line 7x-4y=12
-----------
Solve for y
It'll be in slope-intercept form, y = mx + b
The coefficient of x is the slope, m
-----
b is the y-intercept

DESCRIBE a linear EQUATION: slope, intercepts, etc
Equation
describes a sloping line. For any
equation ax+by+c = 0, slope is
.
X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 12/7 = 1.71428571428571.
Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 12/-4 = -3.
Slope is -7/-4 = 1.75.
Equation in slope-intercept form: y=1.75*x+-3.
