We would read "Δy" as...
"triangle y"
"delta y" or "change in y"
y-intercept, where it crosses the y-axis
"slope"
We would read "Δx" as...
"triangle x"
"delta x" or "change in x"
the x-intercept where it crosses x-axis
"slope"
"slope" is...
a measure of how flat a line is
how much the line starts with
Δy / Δx - you divide the change in y over the change in x
none of the above
if slope is greater than 1, the line will be...
almost flat, but still going upward
more steep, going upward
more steep, going downward
almost flat, but going downward
if slope is less than 0, the line will be...
almost flat, but still going upward
more steep, going upward
going downward as you move left to right
completely vertical or completely horizontal
If slope is between 0 and 1...
the line will be very steep, going upward
the line will be almost flat but still going upward
the line will be very steep, going downward
the line will be almost flat but going downward
the letter used to represent the slope in an equation is...
m
b
Δ
y
the y-intercept is...
where the line crosses the y axis, when x=0
where the line crosses the x axis
the y-value when y=0
the x-value when y=0
In an equation, the y-intercept is usually represented by the letter...
y
i
m
b
Which of the following is slope-intercept form?
y = bx + m
y = mx + b
y = m + x + b
y + m + x = b
Why is the table linear or why not?
linear because it decreases by 10 each time
nonlinear because it goes from 9 to 14 to 19
nonlinear because 14 - 9 = 5, and 19 - 14 = 5, and they match
linear because it changes by a different number each time
If we know the slope is 2 and the y-intercept is 3, write an equation for a line in slope-intercept form (y=mx+b)
Rate your performance on a scale of 1 to 4, with 1 being #1 and 4 being pretty good.
1 - I'm number 1!
2 - I think I came in second place!
3 - I think I'm the second highest!
4 - I did the highest!
None of the above
