Answer:
<h2>y = 2.4x - 7.8</h2>
Step-by-step explanation:
The slope-intercept from of an equation of a line:
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
The formula of a slope:
<em>(x₁, y₁), (x₂, y₂)</em><em> - ponts on a line</em>
<em />
We have two points (7, 9) and (2, -3).
Substitute:
Put the value of the slope and the coordinates of the point (7, 9) to the equation of a line:
<em>subtract 16.8 from both sides</em>
Finally we have:
Answer:
10, because only 5 and 5 are positive which means a increase or gained
Answer:
(x-7)^2 + (y+3)^2 = 49
Step-by-step explanation:
The general equation for a circle is given by
(x-h)^2 + (y-k)^2 = r^2
where ( h,k) is the center and r is the radius
(x-7)^2 + (y- -3)^2 = 7^2
(x-7)^2 + (y+3)^2 = 7^2
(x-7)^2 + (y+3)^2 = 49
