Unit 5 Flashcards
1
Q
slope-intercept form
A
y=mx+b
2
Q
point slope form
A
y-y1=m(x-x1)
(x1, y1) is ANY POINT on the line!
parentheses are NOT SQUARED (cause it’s a line!)
3
Q
standard parabola form
A
y=a(x-h)*2+k
(h, k) is ANY POINT on the line!
a is the slope
parentheses are SQUARED (cause it’s a parabola!)
4
Q
vertex form (OF A PARABOLA)
A
y=a(x-h)*2+k
(h, k) is ANY POINT on the line!
a might be 1 and just not be there
parentheses are SQUARED (cause it’s a parabola!)
