Question 258350: In a lab experiment 9 grams of acid were produced in 34 minutes and 19 grams in 43 minutes. Let g be the number of grams and m be the number of minutes. Find a linear equation that you could use to calculate g for any number of minutes?

g=9 m=34
g=19 m=43
(g-g)/(m-m)=slope
19-9/43-34=slope
10/9=slope
g=10/9*m+b
9=10/9*34+b
81=10*34+9b
81=340+9b
81-340=9b
-259=9b
-259/9=b
check
19=10/9*43-259/9
19=430/9-259/9
19=171/9
ok
check
9=10/9*34-259/9
9=(340-259)/9
9=81/9
ok
