Jamie and Hudson took a road trip to the beach. Their total distance traveled after getting on the highway can be found using th
lukranit [14]

The total distance is an illustration of a linear function.

<u>(1) Why the relationship is a function</u>

The relationship is a function because all input values of h, have exactly one corresponding output value of d

<u>(2) The function type</u>

The function is a discrete function, because the number of hours is an integer, and it cannot take decimal values (in this case)

<u>(3) The domain for a drive of 8 hours</u>

The domain is the set of time the girls drive.

So, the domain is: [0,8]

<u>(4) The range</u>

The function is given as:

d = 55h +10

When h = 0,

d = 55(0) +10 = 10

When h = 8,

d = 55(8) +10 = 450

So, the range is: [10,450]

<u>(5) The graph</u>

See attachment

<u>(6) The slope</u>

A linear function is represented as:

y = mx + c

Where:

m represents the slope.

So, by comparison:

Slope = 55

The slope in this case represents the distance travelled per hour

<u>(7) The y-intercept</u>

In (6) above, c represents the y-intercept.

So, by comparison:

c = 10

The y-intercept in this case represents the initial distance

Solve the equation for y. 8x – 9y = 11
Vikentia [17]
8x - 9y = 11    (subtract 8x from each side)

- 9y = -8x + 11  (divide -9 from each side)

\frac{-9y}{-9} = \frac{-8x+11}{-9}

y = \frac{-8}{-9} x - \frac{11}{9}

D. y=\frac{8}{9} x - \frac{11}{9}
