Find the slope of the given points (2,5) and (8,-3) and write the equation

max2010maxim [7]

Answer:

Slope = $\frac{-4}{3}$

4x + 3y = 23

Step-by-step explanation:

slope = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{-3-5}{8-2} =\frac{-8}{6} =\frac{-4}{3}$

The equation:

$\frac{y-y_{1} }{x-x_{1} }=m$ m is the slope

$y-y_{1}=m(x-x_{1} )$

y - 5 = -4/3 (x - 2) Multiply both sides by 3

3y -15 = -4 (x - 2)

3y - 15 = -4x + 8

3y + 4x = 8 + 15

3y + 4x = 23

4x + 3y = 23

Salinas car use 15.6 gallons of gas to go 234 miles at this rate how many gallons will it take her to go 480 miles?

Whitepunk [10]

Salinas will use 32 gallons for 480 miles

<h3>How to calculate the number of gallons required ? </h3>

Salinas used 15.6 gallons of gas for 234 miles

Miles can be described as the distance travelled by an object or an individual

The first step is to calculate the number of miles travelled using 1 gallon

15.6= 234

1= x

cross multiply both sides

15.6x= 234

x= 234/15.6

x= 15

1 gallon will take her 15 miles

Therefore, the number of gallons required for 480 miles can be calculated as follows

1= 15

x= 480

cross multiply both sides

15x= 480

x= 480/15

x= 32

Hence Salinas will require 32 gallons for 480 miles of the journey
