The equation written in slope-intercept form is y = (1/3)x -9
<h3>What is a linear Equation ?</h3>
A linear equation is that which can be represented in the form of y =mx +c , m is the slope and c is the intercept.
The given equation is
y+6 = 1/3(x-9)
To determine the slope and the intercept this equation needs to be solved
y+6 = (1/3)x - 3
y = (1/3)x -9
Therefore this is the slope intercept format , here
the slope = 1/3
intercept = -9

Answer:
Step-by-step explanation:
-Given that 
-We determine the z-value corresponding to the 95% confidence level:
-The margin of error is the degree of error from the real value and is calculated as follows:
Hence, the margin of error is 
If the equation x² + 16x + c = 0 has only one real solution, the value of c is equal to 64.
<h3>Discriminant: </h3>
The quadratic formula includes the discriminant, which comes after the square root. The discriminant of a quadratic equation is important because it indicates the quantity and kind of solutions.
The formula for the Discriminant of a Quadratic Equation ax²+bx +c = 0 is given by
<h3> Discriminant Δ = b² - 4ac </h3>
Here we have
x² + 16x + c = 0 equation has only one real solution
Compare given equation with ax²+ bx + c = 0
=> a = 1, and b = 16
As we know when an equation has only one real solution
then its Discriminant will be equal to zero
=> b² - 4ac = 0
By the above values,
=> 16² - 4(1)c = 0
=> 256 - 4c = 0
=> 4c = 256
=> c = 256/4
=> c = 64
Therefore,
If the equation x² + 16x + c = 0 has only one real solution, the value of c is equal to 64.
