Which graph best represents the equation y=-3x-2

The Third Choice

The first thing we have to notice that the given equation is written in Slope-Intercept Form. We can see that the y-intercept is . The lines of Second and Third choices intersect the y-axis at . We also have to notice that the slope of given equation is negative. This means that when increases has to decrease. For the line of the second choice, increases when increases. So, the third choice.

To know more about the slope form, you can refer to my Answer from this question:

To know more about y-intercepts, you can refer to my Answer from this Question:

the given 6 = w/p is equivalent to 6p = w, where w is the total area of the walls and p is the area covered by a single can of paint.

knowing that 6 cans of paint will be needed, 6p = w becomes 6(6) = w = 36.   this tells us that the total area to be painted is 36 square units.
