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. -9/-3 = 3.
Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is -9/4 = -2.25.
Slope is --3/4 = 0.75.
Equation in slope-intercept form: y=0.75*x+-2.25.
