Answer:

{ \rm{y = { \boxed{  \blue{- 4}}x + { \boxed{ \blue{5}}}}}}

Step-by-step explanation:

Consinder points (0, 5) and (1, 1):

{ \rm{slope =  \frac{(1 - 5)}{(1 - 0)} =  \frac{ - 4}{1}  }} \\  \\ { \underline{ \rm{ \: m =  {}^{ - }4 \:  }}}

• From general equation of a line:

{ \tt{y = mx + c}}

  • m is the slope
  • c is the y-intercept

• Considering point (1, 1)

{ \rm{1 = ( {}^{ - }4 \times 1) + c }} \\ \\  { \rm{1 =   {}^{ - }  4 + c}} \\  \\ { \rm{c = 5}}

• Therefore;

{ \boxed{ \rm{ \: y =  {}^{ - }4x + 5 }}}

The charge to rent a trailer is ​$25 for up to 2 hours plus ​$9 per additional hour or portion of an hour.

Find the cost to rent a trailer for 2.8 ​hours, 3 ​hours, and 8.7 hours.

Then graph all ordered​ pairs, (hours,​ cost), for the function.

Answer:

ordered pair = (2.8, 34)

ordered pair = (3, 34)

ordered pair = (8.7, 88)

Step-by-step explanation:

Charge for 2.8 ​hours:

$25 for 2 hours

$9 for 0.8 hour

Total = $25 + $9

Total = $34

ordered pair = (2.8, 34)

Charge for 3 ​hours:

$25 for 2 hours

$9 for 1 hour

Total = $25 + $9

Total = $34

ordered pair = (3, 34)

Charge for 8.7 ​hours:

$25 for 2 hours

$9 for 1 hour

$9 for 1 hour

$9 for 1 hour

$9 for 1 hour

$9 for 1 hour

$9 for 1 hour

$9 for 0.7 hour

Total = $25 + $9 + $9 + $9 + $9 + $9 + $9 + $9

Total = $88

ordered pair = (8.7, 88)

The obtained ordered pairs are graphed, please refer to the attached graph.
