The product in simplest form is (x - 4)
<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>

We have to find the product in simplest form
In the given expression,
2x + 8 = 2(x+ 4)
We know that,

Therefore,

Substitute these in given expression

Cancel the common factors,

Thus the product in simplest form is (x - 4)
In the slope intercept form equation of a line (y=ax+b) a represents the slope, and b represents the intercept, which is -5. Thus, we know y=ax-5. The slope can be found by creating a fraction with the change in y value on top, and the change of x value on the bottom. If we have two points (4, 1) and (0, -5) we can put this into a fraction -

, which simplifies down to -6/-4, or 3/2. Thus the answer is f(x)=

x-5<span />
