The slope of the line below is 5. which of the following is the point-slope form of the lne?

irga5000 [103]

Point-slope form of a line is

y=mx+b

where m is the slope and b is your y intercept

So, if the slope is 5, then that is your m value

y=5x+b

To find the value of b, that is just the value of where the line passes the y axis

Answer:

Option B.

Step-by-step explanation:

The given expression is

$\dfrac{10x^2-32}{4}$

We need to find the simplified form of given expression.

Taking out GCF from the numerator.

$\dfrac{2(5x^2-16)}{4}$

Cancel out common factors.

$\dfrac{5x^2-16}{2}$

The expression $\dfrac{5x^2-16}{2}$ is the simplified form of given expression.

Therefore, the correct option is B.
