You have to be very careful how you set this up. For every girl (who counts as 1) there are 3 boys (who count as 3). The total number in the proportion is 3 + 1 =4. You are given a total, but that is both boys and girls. That's why you need the 4.
3/4 = x / 236 Cross multiply
4x = 3 * 236
4x = 708 Divide by 4
x = 708/4
x = 177
There are 177 boys at the school and 236 - 177 = 59 girls.

Answer:
The slope of this line would be 3.
Step-by-step explanation:
To find the slope of any line, use the slope formula and the points given.
m(slope) = (y2 - y1)/(x2 - x1)
m = (4 - 1)/(3 - 2)
m = 3/1
m = 3
