Answer:
<em>-</em><em>7</em>
Step-by-step explanation:
<em>a=9 a2=2 a3=-5 a4=-12 </em>
<em>d = a4-a3 ,a3-a2, a2-a.</em>
<em>so</em><em>: </em>
<em>d = -12-(-5) =-12+5 =-7</em>
<em>also;</em>
<em>d = -5-2 = -7</em>
<em>and </em>
<em>d</em><em>= 2-9 =-7</em>
<em> so the common difference is -7</em>
The equation of the line will be y = 2x - 2.
<h3>What is an equation of the line?</h3>
A linear equation with a degree of one is referred to as a line equation. Two variables, x, and y are present in the equation of the line. The third parameter is the line's slope, which indicates the line's elevation.
The general form of the equation of the line is given as:-
y = mx + c
Given that the equation of the line is passing through the point ( -2,0) and the slope of the line is 2.
The equation of the line will be calculated as:-
y = mx + c
-2 = 0 + c
c = -2
y = mx + c
y = 2x - 2
Therefore, the equation of the line will be y = 2x - 2.

Answer:
Step-by-step explanation:
in a right triangle a^2+b^2=c^2,
where a and b are the legs
where c is the hypothenuse
9^2= b^2+3^2
81-9=b^2
b^2=72
b=8.48
