10) Do the following graphs represent a linear or non-linear relationship? How do you know this?
Answer:
The total number of people in the room is: 28 + 21 = 49 (people)
The percentage of women in the room will be: (28 . 100)/49 ≈ 57%
So the proportion of women in relation to the total number of people is:
57/100 = 28/49

Answer:
2nd option
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (-
, 0) and (x₂, y₂ ) = (0,
)
m =
=
=
and c =
, then
y =
x +
( multiply through by 4 to clear the fractions )
4y = 2x + 3 ( subtract 4y from both sides )
0 = 2x - 4y + 3 , that is
2x - 4y + 3 = 0 ← equation of line
