• Unit 1 Day 1 Notes: Name:______________________ Graphing Equations of Lines & Function Notation Date:______________ SLOPE INTERCEPT FORM OF A LINE:_______________________

What is the equation of the line in the graph displayed below:

Let’s graph the equation 1 2 3

y x

Slope:______ Y-Intercept:_______

Domain:_________________ Range:__________________

Let’s graph the equation 2 4y x .

Slope:______ Y-Intercept:_______

Domain:_________________ Range:__________________

Let’s graph the equation 2 3 6x y .

Remember it MUST be in slope intercept form in order to graph!

Slope:______ Y-Intercept:_______

Domain:_________________ Range:__________________

Slope:_____ Y-Intercept:____

Equation:___________________

Write the slope as a fraction & y-intercept as a point!

• Let’s practice putting equations in slope-intercept form (SOLVE FOR Y!!). Then state the slope and y-intercept.

10 3y x Slope:_____ Y-Intercept:____

3 4 12x y Slope:_____ Y-Intercept:____

2 7 14x y Slope:_____ Y-Intercept:____

Graph a Vertical line: Graph a Horizontal line:

Find 3 points on your line: Find 3 points on your line:

Using FUNCTION NOTATION

Given f(x) = x2 – 2, find: f(5)= f(-5)= f(0)=

Given g(x) = 2x + 7, find: g(4)= g(-4)= g(a)=

Given h(x) = -2x2+ 7x - 11, find: h(2)= h(2a)= 3h(-3)=

A little more of a challenge: Given f(x) = 2x + 1, find -4[f(3) – f(1)]. ##### Graphing Linear Equations Chapter Graphing Linear Equations Chapter Problems Linear Equations Classwork ... Graphing Linear Equations using intercepts
