For this case we have that by definition, an equation of the line of the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
We have two points through which the line passes, then we find the slope:
Then, the equation is of the form:
We substitute a point and find b:
Finally we have:
y = x-4
Answer:
Option B
Possible values of x is -4 or -16
<h3>How to solve?</h3>
+ 20x +100 = 36
+ 20x + 100-36 = 0
+ 20x + 64 = 0
Using middle term split
In this method splitting of middle term in to two factors, In Quadratic Factorization using Splitting of Middle Term which is x term is the sum of two factors and product equal to last term.
+ 4x + 16x + 64 = 0
x(x+4) + 16(x+4) = 0
taking common (x+4)
(x+4)(x+16) = 0
Either
x+4 = 0
⇒ x = -4
or (x+16) = 0
⇒ x = -16
Thus possible values of x is -4 or -16
