To graph a line, first put the equation into slope-intercept form:

. So what can we do with our equation,

, to get it into slope-intercept form? If we divide both sides of the equation by

, we get

. This gives us several pieces of information. Remember that the
constant term, the one without a variable, tells us the y-coordinate of the y-intercept. The y-intercept is where the graph crosses the x-axis. So here, the constant term is 2; so the y-intercept is
(0,2). That is one of the points. Now what does the slope represent? It is rise/run. Here it is -1/3. So from our y-intercept, (0,2), we can go down one unit and to the right 3 units. This new point is
(3,1). From that point we can apply that again: go down 1 and right 3 units to get another point,
(6,0).
Step-by-step explanation:
Let the number of girls = x
Therefore, no. of boys =

Thus, no of boys in the class is 35.
1. 16
2. 10
3. ?
4?
for 3 and 4 I think you use a protractor
15 I think 1.25 x 12 = 15
