View: True Lyric Explanation

1st verse:
y = mx + b
Change the equal sign to an inequality
Showing a range of true possibilities
It’s not just numbers on a line
Y is greater than or greater than or equal to me
Or less than or less than or equal you’ll see
Y on the left and alone, think positively
Symbol turns, from a negative divide

Chorus:
Use the y-intercept and slope to draw a solid line
Like greater than or equal to
Or dotted line, like less than
Then shade above the line or below
We shade above with any greater than
Shade below with any less than
Including less than or equal to
We’re, shading the points that make this true

2nd verse:
If y is greater than, it’s a dotted line
We shade above to identify
All the ordered pairs, or coordinates I…
Continue to prepare
Y is less than or equal to - solid line
We shade below to identify
All the ordered pairs along that line
Or coordinates down there

Bridge:
Plug in any coordinate along the line
Or in a shaded region, that would be just fine
And check your work to find a true statement
Like 7 is greater than or equal to 5
Or pick an ordered pair on the shady spot
But not along the dotted line, we don’t work with that
Now check your work to find a true statement
Like 2 is less than 9
