Linear relationships can be expressed in a graphical format where the variable and the constant are connected via a straight line or in a mathematical format where the independent variable is multiplied by the slope coefficient, added by a constant, which determines the dependent variable.
Answer:
x = ± 10
Step-by-step explanation:
to solve the equation let y = 0 , that is
100 - x² = 0 ( add x² to both sides )
100 = x² ( take square root of both sides )
±
= x , that is
x = ± 10
The point-slope equation of the line is 
Step-by-step explanation:
The form of the point-slope equation is
, where
- m is the lope of the line
is a point lies on the line
The slope of a line
, where
and
are two points on the line
∵ The line through (2 , 3) and (7 , 4)
∴
= 2 and
= 7
∴
= 3 and
= 4
- Substitute these value in the rule of the slope
∵ 
∴ the slope of the line is 
Let us substitute the value of the slope and the coordinates of point
in the form of the equation
∵ 
∵
= 2 and
= 3
∵ 
∴ 
The point-slope equation of the line is
