slope, lines, intercepts Flashcards
1
Q
what is and how to find slope
A
rise + run
how steep a line is
rise then run so y then x
2
Q
what is slope intercept form
A
y= mx + b
3
Q
what is m in
y=mx + b
A
slope
4
Q
what is the b in
y= mx + b
A
y- intercept
5
Q
how to find slope of a line
A
rise y2-y1
run x2- x1
6
Q
how do you know if its a postive slope
A
right to left = slope is postive
7
Q
how do you know if its a negitive slope
A
left to right = slope is negitive
8

A
where the line crosses y in the graph
10
Q
