2.Which type of variables are usually on the y-axis and represent output?

3.Which type of variables are usually on the x-axis and represent input?

4.Which type of slope is represented on a graph as a horizontal line?

5.Find the slope of 2x + 4y = 12

(and the pic is a different question)

And for the very last pic there is a passage to go with it so here it is!

10. A study was done to investigate the use of text messaging over time. The table shows the relationship between the number of years after 2005 and the number of text messages an average person sent monthly.

1. I would call quadrants i, ii, iii, iv as a, b, c, d

2.Which type of variables are usually on the y-axis and represent output?
they usually are the dependent variables, that is, they depend on the x value, such as velocity, price, income.

3.Which type of variables are usually on the x-axis and represent input?
those are the independent variables such as time, distance, price.

4.Which type of slope is represented on a graph as a horizontal line? 
the slope of an horizontal line is zero.

5.Find the slope of 2x + 4y = 12
the general form of the line is:
4y = - 2x + 12
y = -(1/2)x + 3

hence the slope is -1/2
