The equation that pases through these sets of points would be
y = 2x + 3
The slope of the equation is 2, and the y-intercept is 3.
2c+5=c+8
2c-c=8-5
1c=3
c=3/1
c=3
1. 42 5/8 + 39 3/5
Find common denominator for the fractions and rewrite them using the common denominator:
5/8 = 25/40
3/5 = 24/40
25/40 + 24/40 = 49/40 = 1 9/40
1 9/40 + 42 + 39 = 82 9/40 feet
2. 9/40 = 0.225, plus 82 feet = 82.225 feet, this is less than 82.5, so the 8th graders earned the 50 points.
3. The equation would be the total of completed jumps divided by the total number of attempts:
(2 +4 + 1) / (3 + 6 +4) = 7/13 = 0.538 average.
4. 0.538 is greater than 1/2 ( 0.50), so the 8th graders earned 50 points.
