Unit 5

Question 1

slope-intercept form

Answer 1

y=mx+b

Question 2

point slope form

Answer 2

y-y1=m(x-x1)

(x1, y1) is ANY POINT on the line!
parentheses are NOT SQUARED (cause it’s a line!)

Question 3

standard parabola form

Answer 3

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!)

Question 4

vertex form (OF A PARABOLA)

Answer 4

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!)
