D ÷ T = S
A is correct because to find the speed you have to divide the distance by the time. The answer is 4.

The answer is A because the equation is 40/10 which would give you 4 and it asks m/s.

Find the equation of the line passing through the points (1,5) and (3,9)

Arada [10]

Answer:

$\boxed{\sf{2}}$

Step-by-step explanation:

Use the slope formula.

$\underline{\text{SLOPE:}}$

$\Longrightarrow: \sf{\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{Rise}{Run} }$

$\sf{y_2=9}\\\\\\\sf{y_1=5}\\\\\\\sf{x_2=3}\\\\\\\sf{x_1=1}$

$\sf{\dfrac{9-5}{3-1} }$

Solve.

$\sf{\dfrac{9-5}{3-1}=\dfrac{4}{2}=\boxed{\sf{2}}$

Therefore, the slope is 2, which is our answer.

I hope this helps. Let me know if you have any questions.
