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. 0/7 = 0.
Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 0/1 = 0.
Slope is -7/1 = -7.
Equation in slope-intercept form: y=-7*x+0.
y=-7x is just the line that passes through the origin with a slope of -7
I hope this helps!
