Complete the expression that represents the table<br><br> Y=___x

bezimeni [28]

Answer:

The equation that represents the table is:

$y=\frac{9}{2}x$

Step-by-step explanation:

Taking two points from the table

(2, 9)

(4, 18)

$\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(2,\:9\right),\:\left(x_2,\:y_2\right)=\left(4,\:18\right)$

$m=\frac{18-9}{4-2}$

$m=\frac{9}{2}$

As the slope-intercept form is

$\:y=mx+b$

Plugging (2, 9) to find the y-intercept 'b'

$9=\frac{9}{2}\left(2\right)+b$

$\mathrm{Switch\:sides}$

$\frac{9}{2}\left(2\right)+b=9$

$\mathrm{Remove\:parentheses}:\quad \left(a\right)=a$

$\frac{9}{2}\cdot \:2+b=9$

$9+b=9$

$b=0$

so the equation becomes

$\:y=mx+b$

$m=\frac{9}{2}$

$b=0$

$y=\frac{9}{2}\left(x\right)+0$

$y=\frac{9}{2}x$

Therefore, the equation that represents the table is:

$y=\frac{9}{2}x$

The graph of the equation is also attached below.

Answer:

Stacy's rate is 18 miles over the last 2 hours

Step-by-step explanation:

On a bicycle, Stacy rides for 8 hours and is 74 miles from her house. After riding for 10 hours, she is 92 miles away

Let x be the number of hours and y be the number of miles

Stacy rides for 8 hours and is 74 miles , (8,74)

riding for 10 hours, she is 92 miles away (10,92)

To find the rate per hour we find slope

$slope =\frac{y_2-y_1}{x_2-x_1} =\frac{92-74}{10-8} =\frac{18}{2}$

slope 18 divide by 2 represents 18 miles for every two hours

so Stacy's rate is 18 miles over the last 2 hours
