Question 1205599
Very routine exercises.

{{{y=mx+b}}}


Read the slope and the y-axis intercept from the equation directly.
slope, m
y-axis intercept, (0,b)


If you want x-axis intercept, solve for x and set y equal to 0.


something of a form x=k in which x is variable but k is a known constant, then x is not really "variable"; this is a vertical line for a graph and x=k HAS NO SLOPE, or slope does not exist.
