Graphing Functions in Standard Form
How do we graph a
function?
Graph the function:
2x  3y  6
.
STEP 1: Find x-intercept:
Cover up the term with a ‘y’ to
get x intercept
STEP 2: Find y-intercept:
Cover up the term with an ‘x’ to
get y -intercept
x  intercept

,

y  intercept

STEP 3: Plot the intercepts.
,

Plot the x-intercept on the x-axis!
Plot the y-intercept on the y-axis!
Note the resulting values must be integers in order to use “cover up”
1)
Graph the function:
5 x  2 y  10
.
STEP 1: Find x-intercept:
x  intercept
