Point (9, -6)
General Formulas and Concepts:
<u>Algebra I</u>
Point-Slope Form: y - y₁ = m(x - x₁)
- x₁ - x coordinate
- y₁ - y coordinate
- m - slope
Step-by-step explanation:
<u>Step 1: Define</u>
y + 6 = 10(x - 9)
<u>Step 2: Break Function</u>
<em>Identify Parts</em>
Slope <em>m</em> = 10
Point (9, -6)
Using the data below, what is the equation for the line of best fit? Remember, put your answer in y = ax + b form and round any decimals to two places.
Answer:
D
Step-by-step explanation:
u make subject of fomula x then divide by
Let Xavier's favourite fraction be a/b, Yessie's favourite fraction = b/a and Zorro's favourite fraction = c/d,
c/d x a/b = 12/35 . . . . . . . . (1)
c/d x b/a = 15/7 . . . . . . . . (2)
(1) x (2) = c/d x a/b x c/d x b/a = 12/35 x 15/7
c^2 / d^2 = 36/49
c^2 = 36
c = 6
d^2 = 49
d = 7
Xaviers favourite fraction = 12/35 / 6/7 = 2/5
Yessies favourite fraction = 5/2
Zorro favourite fraction = 6/7
