The function y=12x when plotted using the interval of
x-values from -1 to 3 will give a straight line on a given plot. Therefore the
function rule of a line y=mx+b can be used to describe the growth or
progression of this function. The rule states that y is directly proportional
to x.

I’m attaching a photo. For each of these, start by multiplying both sides of the inequality by what’s in the denominator.
When drawing of the number lines, the circle is filled in if the any quality has an “equal than.” Otherwise, the circle is left open.
When dividing by a negative number, the direction of the inequality flips. Greater than becomes less than, and vice-versa.
