The table below shows some values that satisfy a linear function.

Makovka662 [10]

Answer:

1.5

Step-by-step explanation:

Given the pair of points on the table.

Now the formula for slope, $m=\dfrac{y_2-y_1}{x_2-x_1}$

To calculate the slope we only require two pair of points.

Let us take: $(x_1, y_1)=(-5,0)$ and (x_2, y_2)=(-3,3)$

$m=\dfrac{3-0}{-3-(-5)}\\=\dfrac{3}{-3+5}\\=\dfrac{3}{2}\\m=1.5$

The slope of the linear function represented by the values in the table is 1.5.

Note: You can use any two set of values. The result will be the same.

Jen butler has been pricing speed-pass train fares for a round trip to New York three adults and four children must pay $118 two

vitfil [10]

Answer:

Adult’s ticket = $ 18

Child’s ticket = $ 16

Step-by-step explanation:

Adults: x

Children: y

(3x + 4y = 118) * (2) = 6x + 8y = 236

(2x + 3y = 84) * (-3) = -6x - 9y = -252

Add both equations:

-y = - 16

y = 16

3x + 4(16) = 118

3X + 64 = 118

3X = 118 - 64

X = 54/3=18
