Answer:

Step-by-step explanation:
Here, the given expression is

Now, simplifying the brackets, we get
= 
Now, operate on the like terms.
= 
=
Hence, the given expression is simplified to the quadratic equation
Answer:
y = 3x + 8
Step-by-step explanation:
to find slope intercept if we have 2 points use this formula:
find the slope first: m= (y2-y1)/ (x2-x1)
after get the slope, use this formula:
y-y1 = m(x-x1)
Answer:
m= (y2-y1)/ (x2-x1)
= (2-8)/ (-2-0)= -6/-2 = 3
y-y1 = m(x-x1)
y-8 = 3 (x-0)
y = 3x + 8
