## February 12th – 15th

**Standards:**

**MGSE8.EE.5** Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways.

**MGSE8.EE.6** Use similar triangles to explain why the slope m is the same between any two distinct points on a non-vertical line in the coordinate plane; derive the equation y = mx for a line through the origin and the equation *y* = *mx* +*b* for a line intercepting the vertical axis at *b*.

**MGSE8.F.3 **Interpret the equation *y* = *mx* + *b* as defining a linear function, whose graph is a straight line; give examples of functions that are not linear.

**Assessments:**

**Tuesday 2/13 ** – Skills check (writing equation of the line given slope & y-intercept), from a graph and table. (formative assessment)

**Friday 2/16** – Map Task (summative assessment) – We will begin this on Friday 2/16 but I am not sure we will finish it in 1 class period. If we don’t we will continue after the winter break.

**Agenda:**

**Monday** – Writing equation of the line given 1 point on the line and the slope & writing the equation of the line given 2 points on the line.

**Tuesday** – Skills check (formative assessment) . Writing equation of the line given 1 point on the line and the slope & writing the equation of the line given 2 points on the line.

**Wednesday** – Real world application problems. Writing real world situations from a word problem in slope intercept form.

**Thursda**y – Real world application problems. Writing real world situations from a word problem in slope intercept form.
