What is the slope of (8,3) and (-4,-6)?

Nonamiya [84]

Answer: The slope of the line formed by these two points is $\frac{3}{4}$

Step-by-step explanation:

To calculate the slope, we use the formula:

$Slope=\frac{y_2-y_1}{x_2-x_1}$

For the coordinates given:

$x_1=8\\y_1=3\\x_2=-4\\y_2=-6$

Putting values in above equation, we get:

$Slope=\frac{(-6-3)}{(-4-8)}\\\\Slope=\frac{-9}{-12}\\\\Slope=\frac{3}{4}$

Hence, the slope of the line formed from these two coordinates is $\frac{3}{4}$

A.) f(x) = x^2 because 2 > 1. So f(2) = 4.

A is correct.

B.) f(x) = x^2 because 5 > 1. So f(5) = 25.

B is incorrect.

C.) f(x) = 2x because -2 < 1. So f(-2) = -4.

C is incorrect.

D.) f(x) = 5 because x = 1.

D is correct.

So the answer is A and D.
