So I believe you go
( y_{1} - y_{2} )                  (x_{1}- x_{2)}

and substitute x an y like this 
  
(1-7)         (7-1)
and get a slope of -9/6 

Sorry If I got it wrong,but I hope I helped

What is the slope and the y-intercept of -1.7x-1.9y=5.8
Julli [10]

Answer:

The slope is -0.89 and the y-intercept is (0, -3.05).

Step-by-step explanation:

To find the slope and y-intercept, convert the equation to y=mx+b where m=slope and b=y-intercept.

Convert the equation by rearranging the terms using inverse operations.

-1.7x - 1.9y = 5.8                                 Add 1.7x to both sides.

+1.7x                     +1.7x

------------------------------------

       -1.9y = 5.8 + 1.7x                         Divide both sides by -1.9.

            y= - 0.89 x - 3.05

This is now in y=mx+b and m=-0.89 and b=-3.05.

The slope is -0.89 and the y-intercept is (0, -3.05).

A cab in NYC charges you $1.25 a mile and a flat fee of $4 to ride in the cab. A cab in Chicago charges you $0.75 a mile but a f
Vikentia [17]

Answer:

After 4 miles driven by cab the amount would be same in both cities.

Step-by-step explanation:

Let the number of miles be 'x'.

Given:

In NYC

Flat fee of cab = $4

Per mile charge = $1.25

Total cab charges is equal to sum of Flat fee of cab and per mile charge multiplied by number of miles.

Framing in equation form we get;

Total cab charges in NYC = 4+1.25x

In Chicago

Flat fee of cab = $6

Per mile charge = $0.75

Total cab charges is equal to sum of Flat fee of cab and per mile charge multiplied by number of miles.

Framing in equation form we get;

Total cab charges in Chicago = 6+0.75x

Now we need to find number of miles driven so that the amount could same in both cities.

Total cab charges in NYC = Total cab charges in Chicago

4+1.25x=6+0.75x

Combining like terms we get;

1.25x-0.75x=6-4\\\\0.5x=2

using Division Property we will divide both side by 0.5 we get;

\frac{0.5x}{0.5} =\frac{2}{0.5} \\\\x=4

Hence After 4 miles driven by cab the amount would be same in both cities.

The sum of the measures of angle A and angle B is 90 degrees. The measure of angle A is (5x + 10) The measure of angle B is 3x d
Sindrei [870]

Answer:

m<A is 60 degrees

m<B is 30 degrees

Step-by-step explanation:

As the problem says, the sum of m<A and m<B=90 degrees (m<A+m<B=90). The given measures are (5x+10) for <A and 3x for <B

we can substitute (5x+10) and 3x as <A and <B into the equation

so:

5x+10+3x=90

Combine like terms

8x+10=90

subtract 10 from both sides

8x=80

divide by 8

x=10

Now substitute as x

m<A: (5*10+10)=50+10=60 degrees

m<B: (3*10)=30 degrees

Hope this helps!
