this week I learned about solving system of linear equation by elimination.
Ex:

This week i learned about interpreting function and Distance formula
The graph of f is the graph of the equation y = f(x). Use function notation, evaluate functions for inputs in their domains, and interpret statements that use function notation in terms of a context. Recognize that sequences are functions, sometimes defined recursively, whose domain is a subset of the integers.
he distance formula is derived from the Pythagorean theorem. To find the distance between two points (x1,y1) and (x2,y2), all that you need to do is use the coordinates of these ordered pairs and apply the formula that is given to you.

this week i learned about equation and what are some step to solve the equation. I learned 3 different ways to solve the equation. first the slope y-intercept form y=mx+b. second the General form Ax+By+C=0 It always has to be positive in front and it always has to equal zero. Third is the point slope form m(x-x)=y-y or y-y =m(x-x).

This week i learned about the slope,parallel and perpendicular lines, equations of lines, desmos.
A line is said to be perpendicular to another line if the two lines intersect at a right angle.
The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.
Slope is often denoted by the letter m; there is no clear answer to the question why the letter m is used for slope.
for example the rise is 12 and the run is 18 so the slope is gonna be 12/18.
