7x² = 9 + x Subtract x from both sides
7x² - x = 9 Subtract 9 from both sides
7x² - x - 9 = 0 Use the Quadratic Formula
a = 7 , b = -1 , c = -9
x =

Plug in the a, b, and c values
x =

Cancel out the double negative
x =

Square -1
x =

Multiply 7 and -9
x =

Multiply -4 and -63
x =

Multiply 2 and 7
x =

Add 1 and 252
x =

Answer:
Equation of line best fits the scatter plot is y =
Step-by-step explanation:
Let the equation of line be y = mx + c
where m = slope of line and c is the intercept on y -axis
from the graph intercept on y-axis is 108
and the slope of line is given by m =
where (
) and (
) is the points on line
let, points be (4,96) and (18,36)
on calculating this m =
= 
Therefore equation of line best fits the scatter plot is y =
