On his way to the park, Nathan rides his bike at a rate of 0.50 mile per minute for 3 minutes. He stops to admire an antique car
TiliK225 [7]

Answer and Step-by-step explanation:

Although the question is not complete, but with the context of the question, they are most likely going to ask for the total distance travelled or the total time or speed. So let's work on that.

Total time travelled = (3 + 5 + 4) = 12mins

Total speed travelled = (0.50 + 0.00 + 0.40)miles/min = 0.90mile/min

The 0.00 represents the period he was at rest admiring an antique car. At this moment, he was not moving so his speed is 0.

Total distance travelled = total speed x total time = 0.90miles/min x 12min = 10.8miles

What is an equation of the line that passes through the points (4,-2) and (-1,3)
Paraphin [41]

Answer:

<h3>The slope is -1.</h3>

Step-by-step explanation:

To find an equation of the line that passes through the points, you have to use the slope formula.

Slope:

\Rightarrow \sf{\dfrac{y_2-y_1}{x_2-x_1} }

y2=3

y1=(-2)

x2=(-1)

x1=4

Solve.

3--2/-1-4=5/-5=-1

The slope is -1.
