this week in math class I review the final exam. is talk about find the rule and I knew that Arithmetic Sequences also can find the rule. also I learn find how many factor in the equation. for me it is so difficult but I will study hard in this type.

this week I learn systems of linear equations and substation. if they intersect then they are solution. such as 1 solution :m1=/ m2, 2 solution m1=m2, coincident solution also is m1=m2.

this week I learn Equations lines, point slope from of a linear  function and general from of the equation. equations of lines is y=mx+b. m is slope and b is y-inter.

this week I learn Slope of line and Slope formula. I know what is rise and run RISE is Y and RUN  is X. slope formula is RISE/RUN = Y1-Y2/X1-X2. such as A(5,15), B(5,5) Slope is 15-5/5-5=10.the points (2,7),(0,5) and (-1,2) collinear. the points (5,5) and slope is 10. Y-5/X-5=1/-10

This week I learn function notation and  problem solving, this can make me know how to find f(X) and Y=f(X).

This week I learn Inequalities, Domain and Range. I learn how to use Domain and Range and write it down.  Know Domain is X-inter , Range is Y-inter.
