### Linear Equations & Word Problems

Anjie Julseth

(A.) If an answer is an ordered pair, such as (-4, 3), each symbol or number goes in its own box: ( - 4 , 3 )

(B.) When asked to find the slope and y-intercept, put the number for the slope first, a space, then the word "and", another space, then the number for the y-intercept.

(C.) Fractions are written like this: 1/2

 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22
