F(X)=-5x-9
There doesn't seem to be any limitations to the x values, so the domain is all real numbers.

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. -9/5 = -1.8.
Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is -9/1 = -9.
Slope is -5/1 = -5.
Equation in slope-intercept form: y=-5*x+-9.
