of the 30 girls who tried out lacrosse team at Euclid Middle school, 12 were selected. Of the boys who tried out, 16 were select
1 answer:
Ratio of the number of students on the team to the number of students trying out for girls is given by
Ratio of the number of students on the team to the number of students trying out for boys is given by
Since both ratios, simplify to
, thus <span>the ratios of the number of students on the team to the number of students trying out is the same for both boys and girls</span>.

In the future, please post the full problem with all included instructions. After doing a quick internet search, I found your problem listed somewhere else. It mentions two parts (a) and (b)
Part (a) asked for the equation of the line in y = mx+b form
That would be y = -2x+9
This is because each time y goes down by 2, x goes up by 1. We have slope = rise/run = -2/1 = -2. This indicates that the height of the candle decreases by 2 inches per hour. The slope represents the rate of change.
The initial height of the candle is the y intercept b value. So we have m = -2 and b = 9 lead us from y = mx+b to y = -2x+9
----------------------------------------------------------------
Part (b) then asks you to graph the equation. Because this is a linear equation, it produces a straight line. We only need 2 points at minimum to graph any line. Let's plot (0,9) and (1,7) on the same xy grid. These two points are the first two rows of the table. Plot those two points and draw a straight line through them. The graph is below
