A train in Japan can travel 813.5 miles in five hours find the unit rate in miles per hour

Gemiola [76]

Answer:

162.7

Step-by-step explanation:

To find the unit rate you need to find the miles per hour. Since it travels 813.5 miles in 5 hours to find how many it travels in 1 hour you have to divide by 5. When you multiply 813.5 by 5 you get 162.7. Hope it helps

5. (-8, 1) and (0, -5) 6. (-3,-8) and (2,7) write both equations in slope intercept form

Cerrena [4.2K]

Slope-intercept form is as shown here: y = mx + b

(-8, 1) and (0, -5) in slope-intercept form will be y = -3/4x - 5

(-3, -8) and (2, 7) in slope-intercept form will be y = 3x + 1

Graph the line that contains the point (-5,-3) and had a slope of -2

Ipatiy [6.2K]

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

$y = mx + b$

Where:

m: Is the slope

b: Is the cut-off point with the y axis

According to the data of the statement we have to:

$m = -2$

Then, the equation is of the form:

$y = -2x + b$

We substitute the point $(x, y): (- 5, -3)$ and find "b":

$-3 = -2 (-5) + b\\-3 = 10 + b\\-3-10 = b\\b = -13$

Finally, the equation is:

$y = -2x-13$

To graph we place the points $(-5, -3)$ and $(0, -13)$ on the coordinate axis and join the points by a line.

ANswer:

$y = -2x-13$

The graphic is attached.
