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. 25/0.6 = 41.6666666666667.
Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 25/1 = 25.
Slope is -0.6/1 = -0.6.
Equation in slope-intercept form: y=-0.6*x+25.
