Finding Slope
What is the slope of y=2x+9
m=2
A line has a slope of 3 and Y intercept of 1
y=3x+1
What is the y-intercept of y=3x+2
2
What does “HOY” stand for?
Horizontal line, Zero slope, y = constant.
NO (the X value repeats)
What is the slope of y=-1/3x+4
m=1/3
A line has a slope of -1/4 and a y intercept of 4
y=-1/3x+4
In y=−2x+5, does the line rise or fall from left to right?
Fall (it's negative)
What does “VUX” stand for?
Vertical line, Undefined slope, x = constant.
Domain refers to the X or Y values?
X
What is the slope of a horizontal line?
M=0
A line has a y intercept of -3/4 and a slope of 5
y=5x-3/4
If you graphed y=-2, the line would be totally (vertical or horizontal)
Horizontal
A horizontal line passes through the Y axis at -2, what is the line's slope?
0
What is the range of these coordinates? (4,5) (3,5) (9,8) (12,1)
The range is {5, 8, 1}
What is the slope of a vertical line?
Undefined
y=3/2x+5
If you graphed X=-2 the line would be totally (horizontal or vertical)
Vertical
A vertical line passes through the X axis at 7, what is the slope?
Undefined
Find the slope and Y intercept from these two points: (3,9) (12,18)
m = 1, B=6
What is the slope and Y intercept of the line y=6x+7
6, 7
A line has a slope of 3/3 and a y intercept of zero
y=x
What are the steps to getting slope and Y intercept in Desmos?
Click the "Plus" sign to add item, select table.
Put the two coordinates in the table
Select "add regression", select "linear regression"
If the slope comes out to "1/0", why is it considered "Undefined?"
Cannot divide by zero
Simplify (x+2)(x+1)
